Abstract

PURPOSE:To improve the efficiency of excitation by converting most of the beams of an ultraviolet region resulting in the degradation of the beam-collector into a wavelength effective for exciting a laser medium by using a glass material containing a special component. CONSTITUTION:The reflecting mirror of an inner surface is cooled by water in a beam-collector 1. Cooling water flows in a cylindrical glass pipe 3 made of the glass material containing the special component. Beams emitted from a flash lamp 2 are projected to the laser medium through the special glass pipe 3. An excitation rate to the laser medium is improved because the beams of the ultraviolet region noxious for exciting the laser medium are converted into beams of an effective wavelength by fluorescence emitted from the component being contained in the glass pipe 3 and absorbed to the laser medium, and the reflecting mirror located in the inner surface of the beam-collector is also protected from degradation because special glass wavelength-converts ultraviolet beams in the reflecting mirror.
