Discharge exciting pulse laser device |
February 18, 1992 |
| A discharge exciting pulse laser device such as an exima laser device. The laser device is capable of accelerating the timing of rise of the voltage between an auxiliary electrode and one of main electrodes without decreasing a discharge start voltage between the main electrodes, so that |

Laser wavelength stabilization |
April 3, 1990 |
| A laser wavelength is stabilized by deriving a portion of laser beam emitted from a wavelength variable laser oscillator, spectroscopically processing the laser beam portion by means of a wavelength monitor mechanism, measuring a spatial intensity distribution of the spectroscopicall |
