METHOD OF MAKING HIGH RADIATION BRIGHTNESS LASER DIODE Russian patent published in 2013 - IPC H01S5/12 G02B5/32 B82B1/00 

FIELD: physics.

SUBSTANCE: wide-emitter laser medium which is capable of generating multimode optical radiation is formed, having an active waveguide emitting layer, a first end and a second end. A partially transparent mirror is formed at the second end of the wide-emitter laser medium. The wide-emitter laser medium with a partially transparent mirror is placed on a high thermal conductivity substrate. A device is formed for adjusting the mode structure, which is based on a digital planar hologram, having an input end, said device being formed by forming a digital planar hologram at the first end of the wide-emitter laser medium in optical interaction with said hologram; the digital planar hologram is used as an opaque mirror by placing it on the same substrate as the laser medium, as a result of which an optical cavity is formed, and modes of optical radiation of the laser diode are selected, adjusted and amplified according to a give function.

EFFECT: improved optical characteristics of the laser diode without reducing optical power.
