SOLID-STATE LASER FOR PUMPING ACTIVE MEDIUM Russian patent published in 2007 - IPC H01S3/05 H01S3/07 

FIELD: laser physics; devices for pumping liquid, gaseous, and solid active media.

SUBSTANCE: proposed laser characterized in lengthy cylindrical converging pulse radiation wave has optically coupled active element, resonator, resonator Q-factor modulator, active element pumping source, and cooling system. Active element, resonator, and resonator Q-factor modulator are made in the form of n rectangular segments filling circular cylindrical layer, where n is even number. Pumping source in the form of laser diode array is disposed on external surface of active element. Resonator Q-factor passive modulator is made in the form of film disposed on internal surface of active element. Resonator mirrors are applied to active element external surface and to modulator external surface. Active element cooling liquid is disposed in clearance between active element and diode array. Resonator external mirror is transparent to laser diode radiation. Modulator is essentially active electrooptic Q-factor device built integral with active element. Radiation polarization planes of separate laser segments are parallel to cylinder generating line.

EFFECT: enhanced degree of uniformity and homogeneity of pumping active-medium cylindrical flask.
