ABSTRACT:
A solid state laser apparatus and a laser machining apparatus are provided to provide high power laser beam having an excellent condensing performance at high efficiency and with high reliability. In the solid state laser apparatus, a recess is provided in a supporter disposed on a slab side surface at an excitation area corresponding portion. A high reflectance body having a cooling water filtrating groove is disposed in the recess to contact with a slab facing surface with pressure. The supporter contacts slab longitudinal both ends with pressure through a silicon rubber plate which is transparent to excitation light. A transparent silicon rubber O-ring is disposed to extend over an entire peripheral portion of a plane formed by a slab surface including the supporter pressure contacting porting and the supporter so as to seal cooling water and elastically support the slab.
