摘要： PROBLEM TO BE SOLVED: To provide a multicolored solid-state laser, which switches easily to a plurality of kinds of wavelengths for laser beams and can output the laser beams, while the structure of the solid laser is compact and simple. SOLUTION: A rare earth-containing chloride, which makes a wavelength upward conversion light L1 from an excitation light source 1 and can emit the light L1 as a plurality of kinds of peak wavelengths of lights, is used as a laser active medium 2. A filter 4a, which transmits selectively the specified one peak wavelength of the light only from among the plurality of kinds of the peak wavelengths of these lights, is arranged on an optical path between the medium 2 and the optical oscillator mirror on one side of optical oscillator mirrors 3a and 3b, and the specified one peak wavelength of the light L2 is selected and a laser oscillation is made to take place for outputting. It is preferable to use a filter unit 6 of a structure, wherein filters are prepared by the number of lights of peak wavelengths to be selected and only one of the filters can be arranged in a freely exchangeable state on the optical path from among these filters.
