PURPOSE:To obtain a laser beam from a small-sized and large-output laser with good excitation efficiency by a method wherein silid-state laser mediums are arranged on both sides of excitation light sources in the same housing container or the excitation light sources and the solid-state laser mediums are arranged in such a way that the excitation light sources and the solid-state laser mediums are alternately arranged in parallel and the solid-state laser mediums are respectively positioned on the outermost sides. CONSTITUTION:Laser mediums holding excitation light source lamps 2 between them and the mediums 1 are excited by a small number of the lamps 2. Thereby, a plurality if the laser mediums 1 can be housed in the container 6 without enlarging the breadth of the container 6 and a large-output laser can be formed in a small size. Moreover, the volume of the whole housing space including the mediums 1 and the lamps 2 is remarkedly reduced compared to that of the housing container of a conventional laser of a cascade constitution, the whole optical path length from the lamps 2 is shortened, the amount of light, which is absorbed in a cooling medium or the like, is reduced and the excitation efficiency of the lamps 2 is improved. |
