OPTICALLY PUMPED SOLID STATE LASER DEVICE WITH SELF ALIGNING PUMP OPTICS AND ENHANCED GAIN Russian patent published in 2018 - IPC H01S5/04

Abstract RU 2654303 C2

FIELD: electricity.

SUBSTANCE: invention relates to laser equipment. Optically pumped solid state laser device comprises a laser medium in a laser resonator. Laser resonator is formed a first resonator mirror arranged at a first side of the laser medium and a second resonator mirror arranged at a second side, opposite to the first side. First resonator mirror is formed from a distributed Bragg reflector on which a solid state laser medium is located. First and second resonator mirrors are made and arranged to direct laser radiation from the resonator along two different straight paths through the laser medium. Pump laser diode is designed and arranged to optically pump said laser medium by reflecting the pump radiation on a pump radiation reflecting mirror. Pump radiation reflecting mirror is located on the second side and is configured to reflect pump radiation to the laser medium. Pump radiation reflecting mirror and second resonator mirror are integrated into single mirror element.

EFFECT: technical result is enabling alignment, improving gain and realisation of the device in a compact form.
