Item 2.02.  Results of Operations and Financial Condition.

         On April 10, 2007, Electro Scientific Industries, Inc. (the "Company")
announced its financial results for the third quarter of fiscal year 2007. The
Company's press release announcing this event is attached hereto as Exhibit 99.1
and incorporated herein by reference.

Item 8.01.  Other Events

         On April 10, 2007, the Company announced that its Board of Directors
authorized on March 9, 2007 the repurchase of up to $50 million in shares of the
Company's outstanding common stock during the nine-month period following the
Company's announcement of its financial results for the third quarter of fiscal
2007. The repurchases will occur from time to time as market conditions warrant
through transactions in the open market or in negotiated transactions with
brokers or shareholders.

         The Company expects that the share purchase transactions will be
effected pursuant to a plan in conformity with Rule 10b5-1 under the Securities
Exchange Act of 1934. This rule allows public companies to adopt written,
pre-arranged stock trading plans when they do not have material, non-public
information in their possession. The adoption of this stock trading plan will
allow the Company to repurchase its shares during periods when it otherwise
might be prevented from doing so under insider trading laws or because of
self-imposed trading blackout periods.

the registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
