Abstract
The invention relates to light laser processing of materials, in particular to a device for welding, soldering and cutting by means of light and laser beam. The invention is characterized by the following: a device for laser processing of material, comprising a source of laser radiation provided with a focusing optical system and a source for preliminary surface heating placed inside a body. The source for preliminary surface heating comprises a deflector in an emissive focus wherein electrodes of a beamguide are arranged, and a wire guide connecting the laser radiation source to the focusing optical system. The inventive device is provided with a socket containing a quartz light port, mounted in a body placed above the light port, a mirror fixed to the body in a way that makes it possible to move. An orifice for passing the laser beam is embodied in the end face of the deflector. The axis of the orifice intersects the optical orifice of the deflector in the working focus.
