SOLID STATE LASER DEVICE AND SOLID STATE LASER SYSTEM

摘要

PROBLEM TO BE SOLVED: To obtain a solid state laser device in which oscillation efficiency can be enhanced remarkably through a simple arrangement. SOLUTION: A semiconductor laser array is disposed on the side of a solid state laser element, a high reflection coating for the oscillation wavelength of the semiconductor laser array is applied to the end face of the semiconductor laser array on the side opposite to the solid state laser element and the side face of the solid state laser element on the side opposite to the semiconductor laser array thus constituting an optical resonator for pumping light. The solid state laser element is disposed in the optical resonator and pumped by the pumping light.
