Title: Pre-ionization type excimer laser device
Inventor: KAWAMURA SHINICHIRO
IPC: H01S3/038
Filed: 1985-08-19
Abstract: PURPOSE:To obtain an ultraviolet ray pre-ionization discharge type excimer laser of less laser gas contamination by spatially isolating the regions for generating ultraviolet rays for pre-ionization and the main discharge region. CONSTITUTION:Charges are stored in a storage capacitor 4 through a charging coil 5. When a switching device 6 becomes conductive, the stored charges move to a peaking capacitor 8 through the gap between electrodes 9a, 9b for generating ultraviolet rays for pre-ionization. At this time, the ultraviolet light emanating between the electrodes 9a, 9b penetrates through a glass tube 10 which is made of a material having a high transmittance in the ultraviolet region, pre-ionizing the laser gas between main discharge electrodes 1, 2. Since the glass tube 10 is completely isolated from the laser chamber LC, the dust due to the spark between the electrodes 9a, 9b does not mix into the laser chamber LC. Thus, the main discharge region A is completely isolated from the regions for generating ultraviolet rays for pre-ionization.
