摘要： A laser machining device includes a laser oscillator, a laser machining head, an optical fiber transmitting the laser beam oscillated by the laser oscillator to the laser machining head, and an assist gas supply supplying an assist gas of oxygen to the laser machining head. The optical fiber includes a remover removing a clad transmitting beam or reducer for reducing the beam. The laser beam leaked from the core of the optical fiber into the clad is absorbed by a beam absorber at the remover. The structure ensures a high quality surface with no irregularity on the metal surface cut by the laser beam projected from the machining head.

摘要： 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.
