SYNCHRONISATION METHOD OF RULER OF LASER DIODES AND RESONANCE GRIDDED WAVEGUIDE REFLECTOR FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC H01S5/06 H01S5/14 

FIELD: electricity.

SUBSTANCE: resonance gridded reflector in the form of planar waveguide with diffraction lattice on its surface is placed immediately after collimating cylindrical lens installed in front of coated outlet end of ruler of laser diodes. The above lattice is made in the form of corrugation; at that, parameters of waveguide and diffraction lattice are chosen so that two modes spreading in opposite directions can be excited in waveguide. At that, at interaction of the above modes with corrugated surface of waveguide they are emitted to the media adjacent to the above waveguide. Corrugated waveguide surface has anti-reflecting properties excluding spurious oscillation on Fresnel reflection.

EFFECT: providing spatial coherence of emission and increasing compactness of the device.
