Basic characteristic and application of KrF laser pumped by electric discharge

A series of experiments were performed to investigate the fundamental characteristics of a KrF laser pumped by electric discharge. The mode patterns of the laser were observed by a high speed camera. A YBCuO target was irradiated by the same laser and the surface conditions were observed by a microscope. A model x-ray source for pre-ionization which used a wire-initiated plasma source was constructed.
