Title: Narrow-band excimer laser oscillator
Inventor: EURA TAKASHI
IPC: H01S3/106
Filed: 1990-02-23
Abstract: PURPOSE:To obtain a narrow-band excimer laser oscillator whose beam strength distribution is extremely stable by a method wherein the etalon part of a narrow-band excimer laser is kept at absolute zero or at a definite temperature near it. CONSTITUTION:Two kinds of etalons 4, 5 which are elements to form narrow bands and whose free spectral range is different are housed inside a hermetically sealed container 6; they are kept at absolute zero or at a definite temperature near it. When a laser beam passes the etalons 4, 5, one part of the laser beam is absorbed by the respective etalons 4, 5 and is changed into a heat energy. Generally, there is a tendency that a coefficient of thermal expansion becomes zero or extremely small at absolute zero or at a temperature near it. Thereby, the thermal expansion of the etalons 4, 5 can be suppressed to be zero or extremely small, and a laser beam oscillator whose beam strength distribution is stable can be obtained.
