        Item 1. Security and Issuer.
                -------------------

        This Schedule 13D relates to shares of the common stock, par value $0.01
per share (the "SHARES"), of Coherent, Inc., a Delaware corporation (the
"COMPANY"), whose principal executive offices are at 5100 Patrick Henry Drive,
Santa Clara, California 95054.

        Item 2. Identity and Background.
                -----------------------

        This Schedule 13D is being filed by i) Oliver Press Investors, LLC, a
Delaware limited liability company ("OPI"), and the general partner of each of
Davenport Partners, L.P., a Delaware limited partnership ("DAVENPORT"), and JE
Partners, a Bermuda partnership ("JE" and, together with Davenport, the
"PARTNERSHIPS"), ii) Oliver Press Partners, LLC, a Delaware limited liability
company ("OPP"), the investment adviser to each of Davenport and JE, iii)
Augustus K. Oliver ("OLIVER") and iv) Clifford Press ("Press" and, collectively
with OPI, OPP and Oliver, the "FILING PARTIES"). Oliver and Press are United
States citizens and the Managing Members of each of OPI and OPP. The business
address of the Filing Parties is 152 West 57th Street, 46th Floor, New York, New
York 10019.

        None of the Filing Parties have been convicted in a criminal proceeding
(excluding traffic violations or similar misdemeanors), nor has any Filing Party
been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and, as a result of such proceeding, 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.
                -------------------------------------------------

        The amount required by Davenport to purchase the 244,118 Shares owned by
it was $7,205,165.19, including commissions. The amount required by JE to
purchase the 1,628,747 Shares owned by it was $47,425,263.64, including
commissions. All Shares owned by Davenport and JE were purchased in open market
transactions with cash from their respective partnership assets.

        Item 4. Purpose of Transaction.
                ----------------------

        The Partnerships purchased the Shares because OPP, as their investment
adviser, believed the Shares to be undervalued. OPP believes that the Company
has underperformed and has not provided sufficient value to its shareholders.
OPP intends to take over time any and all actions considered appropriate to
realize the value it believes is inherent in the Shares. OPP intends to exchange
views with the Company's management and Board of Directors, and possibly other
shareholders, concerning the strategic direction of the Company. In addition,
OPP may pursue representation of OPP's principals on the Company's Board of
Directors.

        Depending upon OPP's view of the Company's business and financial
prospects and general market conditions, the Partnerships may purchase
additional Shares or dispose of Shares at any time or from time to time.

                Respect to Securities of the Issuer.
                -------------------------------------------------------------
