ITEM 1. SECURITY AND ISSUER

        This statement relates to the Ordinary Shares, par value NIS 0.10 per
share ("ESC Ordinary Shares"), of ESC Medical Systems Ltd. ("ESC"), a
corporation organized under the laws of the State of Israel. The principal
executive offices of ESC are located at Yokneam Industrial Park, P.O. Box 240,
Yokneam, Israel 20692.

ITEM 2. IDENTITY AND BACKGROUND

(a)-(c),(f)     This statement relates to the ESC Ordinary Shares
                acquired by Coherent, Inc. ("Coherent"), a Delaware
                corporation, in connection with the sale of assets from
                Coherent to ESC. Coherent engages in the principal business of
                providing photonics based solutions to the commercial,
                scientific, medical, and telecom markets. The principal
                executive offices of Coherent are located at 5100 Patrick
                Henry Drive, Santa Clara, CA 95054.

                Attached as Exhibit 1 is a chart setting forth, with respect
                to each executive officer and director of Coherent, his or
                her name, business address, principal occupation or
                employment, the name and principal business of the
                organization in which such employment is conducted, and
                citizenship.

        (d)     During the last five years, neither Coherent nor, to the best
                knowledge of Coherent, any executive officer or director of
                Coherent has been convicted in a criminal proceeding (excluding
                traffic violations and similar misdemeanors).

        (e)     During the last five years, neither Coherent nor, to the best
                knowledge of Coherent, any executive officer or director of
                Coherent was a party to a civil proceeding of a judicial or
                administrative body of competent jurisdiction as a result of
                which either Coherent or any executive officer or director of
                Coherent was or is subject to a judgment, decree or final order
                enjoining future violations of, or prohibiting or mandating
                activities subject to, federal or state securities laws or
                finding any violation with respect to such laws.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

        On April 30, 2001, Coherent acquired 5,432,099 shares of ESC Ordinary
Shares in exchange for certain of its assets, principally relating to its
Medical Group, pursuant to the terms of the Asset Purchase Agreement as
amended as of April 30, 2001, by and among ESC Medical Systems Ltd., Energy
Systems Holdings, Inc. and Coherent, dated as of February 25, 2001 (the
"Asset Purchase Agreement").

ITEM 4. PURPOSE OF TRANSACTION

        As described in Item 3 above, the shares of ESC Ordinary Shares
reported in this Schedule 13D/A were acquired by Coherent pursuant to, and at
the closing of the transactions contemplated by, the Asset Purchase Agreement
(the "Closing") on April 30, 2001.

        Coherent acquired the shares of ESC Ordinary Shares at the Closing
for investment purposes in order to obtain a substantial equity position in
ESC. In addition, as set forth in the Asset Purchase Agreement, Bernard
Couillaud, the President and Chief Executive Officer of Coherent, will join
the ESC Board of Directors.

        Coherent has also acquired certain rights and incurred certain
obligations with respect to ESC which are contained in Asset Purchase
Agreement all of which are included in Exhibits 2, 3 and 4 hereto and
described in Item 6 below and incorporated herein by reference. In
particular, the Asset Purchase Agreement sets forth terms pertaining to,
among other things, Coherent's restrictions on acquisition and disposition of
ESC Ordinary Shares, voting

                                       -3-





Scheudle 13D/A                                                       Page 4 of 7


obligations with respect to ESC Ordinary Shares, registration rights and board
representation rights, all as more fully described in Item 6 below.

        Subject to the terms of the Asset Purchase Agreement while it is not
Coherent's present plan or intention to do so, Coherent may seek to acquire
additional shares of ESC Ordinary Shares or other securities of ESC through
open market purchases, privately negotiated transactions, a public tender
offer, a merger, reorganization or comparable transaction, which may include
acquisition of a majority and/or controlling interest in ESC. Subject to the
terms of the Asset Purchase Agreement an acquisition of a majority or
controlling equity interest in ESC by Coherent could result in (i) changes in
the Board of Directors of ESC, (ii) changes in the capitalization or dividend
policy of ESC, (iii) changes in ESC's Certificate of Incorporation or Bylaws
that may impede the acquisition of control of ESC by any person other than
Coherent, (iv) delisting of ESC Ordinary Shares from the Nasdaq National
Market (or other national securities market), (v) termination of registration
of ESC Ordinary Shares pursuant to Section 12(g)(4) of the Act, or (vi) other
events comparable to those enumerated above.

        Alternatively, subject to the restrictions contained in the Asset
Purchase Agreement Coherent may dispose of some or all of the shares of ESC
Ordinary Shares held by it in the open market, in privately negotiated
transactions to third parties, through a public offering upon exercise of the
registration rights outlined below in Item 6, or otherwise, depending upon
the course of action that Coherent pursues, market conditions and other
factors.

        Although the foregoing represents the range of activities that may be
taken by Coherent with respect to ESC, the possible activities of Coherent
are subject to change at any time, subject to the terms of the Asset Purchase
Agreement.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

        As of March 23, 2001, according to the ESC, there were 27,630,898 ESC
Ordinary Shares outstanding.

        (a)     As of the date of this Schedule 13D/A, Coherent was the
                beneficial owner of 5,432,099 shares of ESC Ordinary Shares,
                which represents approximately 16.4% of the outstanding
                shares of ESC Ordinary Shares, all of which were received by
                Coherent upon the Closing.

        (b)     Coherent has shared voting power as to the 5,432,099 shares
                of ESC Ordinary Shares that it beneficially owns with ESC
                Medical Systems Ltd. In accordance with the terms of the
                Asset Purchase Agreement as further described in Item 5
                below, Coherent must cause, for a period of eight (8)
                years following the Closing, all ESC Ordinary Shares held by
                Coherent or its controlled affiliates to be voted in the same
                manner and proportion as the remaining outstanding voting
                shares of ESC Ordinary Shares with respect to each matter
                voted upon. However, Coherent or its affiliates may vote the
                ESC Ordinary Shares held by them in accordance with ESC's
                board of directors' recommendation. In addition, the voting
                requirements do not apply during any suspension of the
                Standstill Period (as defined in Item 6 below) or so long as
                ESC is in breach of its obligations with respect to a
                director designated by Coherent, as described in Item 6 below.

                Coherent has sole power to dispose or direct the disposition of
                the ESC Ordinary Shares; however, pursuant to the terms of the
                Asset Purchase Agreement, Coherent and its controlled affiliates
                may not offer, sell, transfer, assign or otherwise dispose of
                more than 2,700,000 shares of ESC Ordinary Shares to any single
                person or group of affiliates; provided however, that Coherent
                may transfer ESC Ordinary Shares in an open market transaction
                through a "broker" or directly with a "market maker" as such
                terms are defined in the Securities Act of 1933, as amended (the
                "Securities Act"), in which the identity of the buyer is not
                disclosed without regard to the foregoing limitation on the
                amount of ESC Ordinary Shares that may be sold.

        (c)     Coherent has not engaged in any transaction during the past 60
                days in any shares of ESC Ordinary Shares.


                                      -4-

        (d)     No person, other than Coherent, has the right to receive or the
                power to direct the receipt of dividends from, or the proceeds
                from the sale of, the shares of ESC Ordinary Shares beneficially
                owned by Coherent.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
        TO SECURITIES OF THE ISSUER

        In connection with the Asset Purchase Agreement Coherent has agreed
with ESC to several arrangements concerning the ESC Ordinary Shares to be
received thereunder. Pursuant to the terms of the Asset Purchase Agreement
Coherent and its controlled affiliates have agreed not to, knowingly,
directly or indirectly, offer, sell, transfer, assign or otherwise dispose of
(or make any exchange, gift, assignment or pledge of) (collectively,
"Transfer") more than 2,700,000 shares of ESC Ordinary Shares (as such number
shall be adjusted to reflect stock dividends, stock splits or similar
transactions) to any single person or group of affiliates; provided, that
Coherent may transfer ESC Ordinary Shares in an open market transaction
through a "broker" or directly with a "market maker" (as such are defined in
the Securities Act) in which the identity of the buyer is not disclosed
without regard to the foregoing limitation on the amount of ESC Ordinary
Shares that may be sold.

        In addition, in connection with the Asset Purchase Agreement Coherent
has agreed that for the period commencing with the Closing and ending on the
sixth anniversary of the Closing (the "Standstill Period"), neither it nor
any of its controlled affiliates shall, without the prior written consent of
ESC: acquire, offer to acquire, or agree to acquire, directly or indirectly,
by purchase or otherwise become the beneficial owner (as such term is defined
under the Rule 13d-3 of the Act) of (A) any voting securities or direct or
indirect rights to acquire any voting securities of ESC or any subsidiary
thereof, or of any successor to or person in control of ESC in an amount
which, when added to any other voting securities then held by Coherent and
its controlled affiliates (including, without limitation, the ESC Ordinary
Shares), would cause the total amount of voting securities held by Coherent
and its controlled affiliates to exceed twenty three percent (23%) of the
outstanding voting stock of ESC (the "Threshold Amount"), or (B) all or a
significant portion of assets of ESC or of any such successor or controlling
person; provided, however, that the foregoing shall not prohibit Coherent
from presenting and discussing with ESC's board of directors a proposal to
acquire all or substantially all of the assets of ESC or a controlling equity
interest in ESC.

        The limitations set forth in the previous paragraph do not apply if
and for so long as (i) an event of default on a 5% promissory note principal
amount $12,904,000 to be delivered pursuant to the Asset Purchase Agreement
(the "Note") has occurred and is continuing, (ii) a bona fide tender or
exchange offer for voting stock of ESC has been commenced but not withdrawn,
(iii) a blockage of payment obligations of ESC under the Note, in accordance
with its terms, is in effect, (iv) a material breach by ESC of the
Registration Rights Agreement between Coherent and ESC delivered pursuant to
the Asset Purchase Agreement has occurred and not been cured or (v) ESC has
publicly announced a proposed transaction with a third party that would have,
if consummated, the effect of a change of control of ESC (but, in the case of
clause (v), only to the extent necessary to permit Coherent to submit a
proposal for a competing transaction or to purchase Ordinary Shares pursuant
to an offer made available to all shareholders) (any such time during which
the Standstill Period be suspended is hereinafter referred to as "Free
Period"). To the extent Coherent shall have acquired any additional stock or
other securities convertible into stock of ESC during a Free Period, the
percentage of stock held by Coherent immediately after the end of such Free
Period has ended, if greater than 23% of the then outstanding stock of ESC,
shall become the Threshold Amount.

        In addition, in the Asset Purchase Agreement from April 30, 2001 and
so long as Coherent to continues to be the beneficial holder of at least ten
percent of the issued and outstanding shares of ESC Ordinary Shares, ESC has
agreed take all necessary actions so that ESC shall nominate an individual
selected by Coherent (which individual shall be an individual who is either
(i) an officer or member of the Board of Director of Coherent or its
subsidiaries or (ii) reasonably acceptable to ESC) and ESC shall recommend to
its stockholders in writing and include such recommendation in all
stockholder proxy materials or other communications relating to the election
of directors, and shall use all commercially reasonable efforts to ensure,
that such individual be elected to ESC's board of directors at any and all
meetings of or pursuant to any and all written actions by ESC's stockholders.

Schedule 13D/A                                                       Page 6 of 7

obligations with respect to such board member shall terminate to the extent that
Coherent makes, or in any way participates, directly or indirectly, either
individually or as a member of a 13D Group, in any "solicitation" or "proxies"
(as such terms are defined in Regulation 14A promulgated under the Act) in
opposition to the Board of Directors of ESC. Furthermore, upon the occurrence of
any such event, Coherent agreed to cause its designee to resign from the board
of directors of ESC. For purposes of the foregoing, "13D Group" means any group
of persons formed for the purpose of acquiring, holding, voting or disposing of
ESC securities which would be required under Section 13(d) of the Act, and the
rules and regulations promulgated thereunder, to file a statement on Schedule
13D pursuant to Rule 13d-1(a) of the rules and regulations promulgated under the
Act or a Schedule 13G of the rules and regulations promulgated under the Act
pursuant to Rule 13d-1(c) of the rules and regulations promulgated under the Act
with the SEC as a "person" within the meaning of Section 13(d)(3) of the Act if
such group beneficially owned ESC securities representing more than 5% of any
class of ESC securities then outstanding.

        Further, to the fullest extent permitted under applicable law,
Coherent has agreed that for a period commencing with the Closing and ending
on the eighth anniversary of the Closing, Coherent will cause all of ESC
Ordinary Shares held by Coherent or its controlled affiliates to be voted at
any meeting of shareholders of the ESC or at any adjournment thereof or in
any other circumstances upon which the vote of the shareholders of ESC is
sought and to be voted in the same manner and proportion as the remaining
outstanding voting shares of ESC Ordinary Shares are voted in each such
instance; provided, however, that Coherent may, or may cause its affiliates
to, vote the ESC Ordinary Shares held by them in accordance with ESC's board
of directors' recommendation. However, these provisions do not apply during
any Free Period or as long as ESC is in breach of its obligations with
respect to the board member described in the preceding paragraph.

        ESC also agreed to file a registration statement to cover the resale
of the shares of ESC Ordinary Shares to be received under the Asset Purchase
Agreement and those of certain transferees of those shares. ESC agreed to use
its best effort to have such registration statement declared effective no
later than the 30 month anniversary of the Closing and to keep such
registration statement effective until 96 months after the Closing. The
registration statement is subject to customary blackout periods. In addition,
in the event that ESC determines to register any of its Ordinary Shares
(other than in connection with certain business combinations and employee
benefit plans), ESC will include the shares of Ordinary Shares held by
Coherent and certain transferees of Coherent's shares in such registration,
subject to the exclusion of such shares, on a pro rata basis with any other
person with a contractual right to have shares registered, by the underwriter
of any offering for market conditions. The form of Registration Rights
Agreement is attached hereto as Exhibit 3 and incorporated herein by
reference.
