Abstract
A semiconductor laser pumped solid state laser includes a solid laser medium, a semiconductor laser which radiates a pumping laser beam for pumping the solid laser medium, and a light entrance optical system which converges the pumping laser beam in the solid laser medium. The semiconductor laser is disposed with its beam radiating axis inclined to the optical axis of the light entrance optical system so that the pumping laser beam travelling from the semiconductor laser to the solid laser medium and a laser beam reflected at the pumping light inlet side end face of the solid laser medium travel different optical paths. A light-shielding plate which intercepts the laser beam reflected at the pumping light inlet side end face of the solid laser medium is provided between the semiconductor laser and the solid laser medium.
