Abstract:
An ultraviolet laser-generating device, comprising:a laser ray source for irradiating and emitting a basic wave of laser ray therefrom; a wavelength converter device for receiving the basic wave of laser ray emitted from said laser ray source and for converting the laser ray into an ultraviolet laser ray composed of a multiplied high harmonic light of the basic wave of laser ray; and a container which is hermetically sealed and having an inlet window, upon which the basic wave of laser ray emitted from said laser ray source is incident, and an outlet window for emitting the ultraviolet laser ray composed of the multiplied high harmonic light of the basic wave of laser ray, said container including means for discharging residual gas within said container, and means for supplying inert gas which does not chemically react with the laser ray into said container, said container having said wavelength converter device installed therein.
