Semiconductor laser pumped solid state laser

摘要

A semiconductor laser array (2) is arranged on the side of a solid state laser element (1), and an optical resonator to an excitation light is constructed by applying a high reflection coating to an oscillation wavelength of the semiconductor laser array to an end face (201) of the semiconductor laser array positioned on the opposite side to the solid state laser element and to a side (101) of the solid state laser element positioned on the opposite side to the semiconductor laser array. The solid state laser element is arranged on the inside of the optical resonator, and the solid state laser element is excited optically by the excitation light.
