SEMICONDUCTOR DISC LASER Russian patent published in 2012 - IPC H01S5/04 H01S3/94 

FIELD: physics.

SUBSTANCE: laser has an active plane with a mirror coating on the first surface which is attached to a first cold-conducting substrate, an external feedback mirror and a pumping laser. The active plate lies between the mirror coating and the external feedback mirror, which are elements of the optical resonator of the disc laser. The pumping laser has its own stable optical resonator and the wavelength of its radiation is shorter than that of the disc laser. The active plate of the disc laser is one of the reflecting elements of the stable optical resonator of the pumping laser, wherein during reflection of radiation generated in the pumping laser from the active plate, part of the radiation is partially absorbed in the active plate, thereby exciting the disc laser.

EFFECT: high power of radiation and wider spectral range.
