METHOD OF LASER SURFACE PROCESSING AND DEVICE TO THIS END Russian patent published in 2012 - IPC B08B7/00 

FIELD: process engineering.

SUBSTANCE: invention relates to laser processing of materials for use in machine building and instrument making for cleaning surfaces of dirt and undesirable layers, producing preset surface properties for structural materials, and to devices used to this end. Processed surface us subjected to scanning beam of intermittent-pulse laser radiation. Laser beam with time structure made up of intermittent concurrent trains of light pulses is formed. Every pulse train is swept into band. Bands formed by scanning each intermittent concurrent pulse train are coupled. Width of processing band equals crosswise size of laser beam on processed surface. Proposed device comprises interconnected laser and opto-mechanical system Laser generates beam with time structure made up of intermittent concurrent trains of light pulses. Said opto-mechanical system is made up of system that forms homogeneous spatial structure of laser beam and scanning system at the output of which focusing lens is arranged. Computer is connected with synchronising unit connected, in its turn, with laser and scanning system.

EFFECT: higher efficiency of cleaning diverse surfaces.
