MULTI-BEAM LASER RADIATION SOURCE AND DEVICE FOR HANDLING MATERIALS WITH ITS USE Russian patent published in 2017 - IPC H01S3/82 H01S3/05 B22F3/105 B23K26/64 

FIELD: physics.

SUBSTANCE: multiple-beam source consists of a generator and a multi-channel amplifier. Radiation generator comes to the input of the amplifier via the Extender, and then hardened individual fragments of a wide beam of the active element, consisting of laser plates located successively in several parallel ranges. Each plate contains elongated along the longitudinal axis of the plate at the heart of the active material and surrounding it with the side of a dormant shell. The space between all the plates is filled with heat sink elements. The pump radiation is fed through the free narrow faces of the plates. Treated material is placed on the base surface, conventionally divided into sectors according to the number of laser beams. Scanning heads installed over one of the vertices of each sector at an altitude determined by the formula h=d/tgα, where d is the diagonal length of the sector, α - maximum scan angle. To compensate alignment errors of laser heads used rigid frame with a square grid sensors.

EFFECT: invention allows the simultaneous use of a large number of powerful laser beams to speed the processing of large volume products.
