METHOD OF SYNCHRONISING LINE OF LASER DIODES Russian patent published in 2013 - IPC H01S5/06 H01S5/40 

FIELD: physics.

SUBSTANCE: resonance lattice waveguide mirror (3) is placed on a line of laser diodes (1) with a collimating cylindrical lens at an angle to the exit end of a line of laser diodes (1) with a diffraction grating on one or more media boundary surfaces of the resonance lattice waveguide mirror (3) which is in form of a corrugation. The inclination angle, parameters of the resonance lattice waveguide mirror (3) and the diffraction grating are selected such that when radiation of the line of laser diodes (1) with diffraction order of +1 or -1 falls on the resonance lattice waveguide mirror (3), two modes are excited therein, which propagate in opposite directions, upon interaction with the diffraction grating of the resonance lattice waveguide mirror (3) of which they are emitted into the media adjoining said resonance lattice waveguide mirror (3). The resonance lattice waveguide mirror (3) has antireflection properties which prevent spurious generation on Fresnel reflection and provide output of radiation in form of -1 or +1 diffraction order of the radiation of the line of laser diodes (1).

EFFECT: enabling generation of output radiation in form of one diffraction order from a line of laser diodes with divergence defined by its full aperture.
