ABSTRACT:
A semiconductor laser excitation solid laser control device1A according to the present invention is a control device for stabilizing a light quantity of an output light LO of a semiconductor laser excitation solid laser2. The control device1A comprises: a beam splitter11A for branching a laser light emitted from the semiconductor laser excitation solid laser2into the output light LO and a control light LC; a light reception element12for detecting the light quantity of the control light LC branched by the beam splitter11A; and control means13for controlling the light quantity of the laser light emitted from the semiconductor laser excitation solid laser2so that the light quantity detected by the light reception element12will be constant. The beam splitter11A has a transmittance and a reflectivity not depending on the polarization characteristic of the laser light.
