LASER-THYRISTOR Russian patent published in 2015 - IPC H01S5/00 H01L33/00 

FIELD: physics, optics.

SUBSTANCE: invention can be used to generate a controlled sequence of high-power laser pulses. The laser-thyristor includes a cathode region (1), which includes an n-type substrate (2), a wide-band gap n-type layer (3), an anode region (4), which includes a p-type contact layer (5), a wide-band gap p-type layer (6), which is also the optical confinement layer of the laser heterostructure and the emitter, which injects holes into the active region (13), a first base region (7), a p-type layer (8), a second base region (9), an n-type layer (10), a waveguide region (12), Fabry-Perot optical resonator, formed naturally by a cleavage surface (14) coated with an antireflecting coating and naturally by a cleavage surface (15), a first ohmic contact (16), a second ohmic contact (18), a meso-channel (19), a third ohmic contact (20), wherein parameters of the materials of the layers of the first and second base regions satisfy certain expressions.

EFFECT: increasing peak output optical power and reducing the amplitude of the control signal.
