摘要： A solid state laser apparatus is provided to generate a high quality and high power laser beam, and a laser machining apparatus is provided to perform laser machining by a laser beam generated from the solid state laser apparatus. In the solid state laser apparatus, a laser resonator includes a solid state component cooled in a cylindrical pipe by contacting liquid which is introduced through an inflow opening and discharged through an outflow opening, the solid state component having larger refractive index than that of the liquid, a light source turned ON by a power source to excite the solid state component, and an optical system transmitting light from the light source to the solid state component. Further, a surface roughness of the solid state component is adjusted so as to adjust an excitation distribution in a section of the solid state component. The solid state component further includes moving means for moving a reflection mirror and a condensing lens in a direction of an optical axis of the laser resonator, and a housing accommodating an image transferring optical system. A laser beam is generated from the laser resonator, and is externally derived and used to perform the laser machining.
