Solid state laser device and solid state laser device system

摘要

A semiconductor laser array is located beside a solid state laser element, and an optical resonator for excitation light includes a coating highly reflective to an oscillation wavelength of the semiconductor laser array on an end face of the semiconductor laser array, opposite from the solid state laser element and a side of the solid state laser element. The solid state laser element is located inside of the optical resonator, and the solid state laser element is excited optically by the excitation light.
