     This Amendment No. 2 to Schedule 13D (the "Amendment")
amends the Schedule 13D originally filed on September 29, 1999,
amended on October 7, 1999, by II-VI Incorporated, a
Pennsylvania corporation, with respect to its ownership of
common stock, par value $.001 per share, of Laser Power
Corporation, a Delaware corporation.  This Amendment No. 2 is
being filed to amend Items 4, 5, 6 and 7 of the Schedule 13D;
however, Items 1 through 6 are restated in their entirety for
convenience.

Item 1.  Interest In Securities Of The Issuer

     This statement relates to the common stock, par value
$.001 per share (the "Laser Power Common Stock"), of Laser Power
Corporation, a Delaware corporation ("Laser Power").  The
principal executive offices of Laser Power are located at 12777
High Bluff Drive, San Diego, California 92130.

Item 2.  Identity And Background

         This statement is being filed by II-VI Incorporated, a
Pennsylvania corporation (the "Reporting Person").  The Reporting
Person's principal executive offices and principal business are
located at 375 Saxonburg Boulevard, Saxonburg, Pennsylvania
16056.

         The Reporting Person designs, manufactures and markets
optics and electro-optical components, devices and materials for
infrared, near-infrared, visible light, x-ray and gamma-ray
instrumentation.  The Reporting Person's infrared products are
used primarily in high-power CO2 (carbon dioxide) lasers.  These
lasers are used for industrial processing throughout the world.
The Reporting Person manufactures near-infrared and visible-light
products for industrial, scientific and medical applications and
solid-state (such as YAG and YLF) lasers.  The Reporting Person
manufactures and markets solid-state x-ray and gamma-ray detector
products for the nuclear radiation detection industry.  The
majority of the Reporting Person's revenues are attributable to
the sale of optical components for the industrial laser
processing industry.
          The name, business address and present principal
occupation or employment of any corporation or other
organization in which such employment is conducted and the
citizenship of each director and executive officer of the
Reporting Person is set forth in Annex A, which is incorporated
herein by reference.

         Neither the Reporting Person nor, to the best knowledge
of the Reporting Person, any person listed in Annex A, has,
during the last five years, been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors)
or was 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 Reporting Person purchased 1,250,000 shares of the
Laser Power Common Stock on September 21, 1999 for an aggregate
purchase price of $2,750,000.  The Reporting Person

                              3


borrowed 100% of these funds from PNC Bank, National Association,
under an existing credit facility.  This credit facility is
attached as Exhibit 1 and is incorporated herein by reference.

Item 4.  Purpose Of Transaction

         (a) through (i).  The Reporting Person acquired shares
of Laser Power Common Stock to facilitate the acquisition of
control of Laser Power by the Reporting Person by means of a
negotiated merger, the election of a majority of Laser Power's
Board of Directors, a tender offer, or otherwise.  While the
Reporting Person still desires to acquire control of Laser
Power, it has decided not to seek to replace the current
Laser Power Board of Directors with its own nominees and it will
not solicit proxies for the Laser Power 2000 annual meeting
of stockholders.

         The Reporting Person intends to continue to seek to
acquire control of Laser Power and to that end the Reporting
Person may (a) acquire additional securities of Laser Power from
time to time in the open market, in private transactions, or
otherwise; provided that the Reporting Person may dispose of any
or all of the shares of Laser Power Common Stock it owns at any
time in the open market or in private transactions, in any case,
in compliance with applicable securities laws; or (b) seek to
negotiate a merger or other extraordinary transaction with Laser
Power by which the Reporting Person would acquire control of
Laser Power, which would likely result in changes to the
directors and management of Laser Power and which could cause the
outstanding Laser Power Common Stock to be delisted from NASDAQ.
However, the Reporting Person does not presently intend to
(d) seek to change the present board of directors and
management of Laser Power; or (g) seek to change Laser Power's
charter or bylaws to eliminate or modify any provisions which
the Reporting Person determines may impede the acquisition of
control of Laser Power by the Reporting Person.

         The Reporting Person's ability to acquire more than
15% of the outstanding shares of Laser Power common stock
without the approval of Laser Power's Board of Directors is
limited by (i) Section 203 of the Delaware General Corporation
Law and (ii) the Share Purchase Rights Plan adopted by Laser
Power's Board of Directors on October 15, 1999.

Item 5.  Interest In Securities Of The Issuer

         (a)  As of the date hereof, the Reporting Person
beneficially owns 1,252,100 shares, or 14.5% of the issued and
outstanding Laser Power Common Stock, based on 8,644,917 shares
of Laser Power Common Stock outstanding as of January 24, 2000,
as reported in Laser Power's Definitive Proxy Statement filed
January 28, 2000.

         (b)  The Reporting Person has the sole power to vote or
to direct the vote of, and sole power to dispose or direct the
disposition of, 1,252,100 shares of Laser Power Common Stock.

                              4


         (c)  On June 17, 1999, the Reporting Person purchased
100 shares of Laser Power Common Stock on the open market at a
price of $0.75 per share.  On January 7, 2000, the Reporting
Person purchased an additional 2,000 shares of Laser Power Common
Stock on the open market for $2.75 per share.  Both of these
transaction were effected through a broker-dealer.  Other than
these transaction and the transaction described in Item 3 above,
which item is incorporated herein by reference, there have been
no transactions with respect to Laser Power Common Stock within
the last 60 days by the Reporting Person.

         (d)  Not applicable.

         (e)  Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships
         with Respect to Securities of the Issuer.

         There are no contracts, arrangements, understandings or
relationships among the persons named in Item 2 or between such
persons and any other person with respect to any securities of
Laser Power except that Proxima Corporation ("Proxima"), which
was the seller of the shares of Laser Power Common Stock
purchased by the Reporting Person in the transaction described in
Item 3 hereof, was a party to a Registration Rights Agreement
dated June 13, 1997 with Laser Power and Union Miniere, Inc. (the
"Registration Rights Agreement").  Under the Registration Rights
Agreement, a copy of which is attached as Exhibit 4 and is
incorporated herein by reference, Proxima had certain
registration rights with respect to such shares.  Pursuant to an
Assignment and Assumption Agreement dated as of September 21,
1999, a copy of which is attached hereto as Exhibit 5 and is
incorporated herein by reference, Proxima assigned its rights
with respect to such shares under the Registration Rights
Agreement to the Reporting Person in accordance with the terms of
the Registration Rights Agreement.

Item 7.  Material To Be Filed As Exhibits

1.       Amended and Restated Letter Agreement, dated

         Association and II-VI Incorporated for Committed
