FIELD: physics.
SUBSTANCE: disclosed is a laser system for performing laser operations, comprising at least three modules of laser diodes, wherein each of said at least three laser diode modules comprises at least ten laser diodes, each of said at least ten laser diodes is capable of outputting a blue laser beam having power of at least about 2 W and a product of beam parameters below 8 mm·mrad, along a laser beam trajectory, wherein the trajectory of each laser beam is substantially parallel, as a result of which a space is set between laser beams propagating along laser beam trajectories, a spatial alignment means and maintaining brightness of blue laser beams located on all of said at least thirty trajectories of laser beams, wherein spatial alignment and preservation of brightness comprises collimating optics along first axis of laser beam, vertical matrix of prisms along second axis of laser beam and telescopic device, as a result, the spatial alignment and preservation means fills the space between the laser beams with laser energy, resulting in a combined laser beam having a power of at least about 600 W and having beam parameters smaller than 40 mm·mrad. Also disclosed is a laser processing system with an addressable matrix, comprising at least three said laser systems, wherein each of said at least three laser systems is configured to input each of its aligned laser beams into one optical fibre.
EFFECT: as a result, each of said at least three aligned laser beams is configured to extend along the associated optical fibre, said at least three optical fibres in optical communication with the laser head and a control system, wherein the control system comprises a program having a predetermined sequence for delivering each of the aligned laser beams to a predetermined location on the target material.
