Abstract
High output power and stable operation are achieved in a semiconductor laser pumped solid state laser. An LD pumped solid state laser 90 includes a solid state laser crystal 19 such as a Pr:YLF crystal, a plurality of LDs 11 that emits a pumping light beam L to pump the laser crystal 19, a resonator that resonates the light emitted from the solid state laser crystal 19, and a wavelength control means such as a narrow bandpass filter 13 to cause an emission wavelength of the pumping light beam L by the LD 11 to match an absorption peak wavelength of the solid state laser crystal 19.
