LASER DEVICE CONTAINING OPTICALLY PUMPED LASER WITH ELONGATED RESONATOR Russian patent published in 2018 - IPC H01S5/04 

FIELD: electricity.

SUBSTANCE: invention relates to laser equipment. Laser device contains two pumping lasers, one of which is configured to emit the pumping beam independently of the other. Laser device contains amplification element, pumping radiation mirror, and elongated resonator mirror. Elongated resonator mirror contains sub-mirrors, wherein each sub-mirror is configured to focus the resonating beam into the corresponding pumping spot. Pumping radiation mirror is configured to change the first pumping laser pumping beam direction to the first pumping spot on the amplification element and the second pumping laser pumping beam to the second pumping spot on the amplification element. Second pumping spot covers another section on the amplification element, than the first pumping spot. Amplification element has first optical axis extending through the amplification element center, and pumping lasers are arranged symmetrically around the first optical axis on the common with it heat sink. First optical element comprises second optical axis extending to the elongated resonator mirror center. First optical axis is independent from the second optical axis so, that small inclination angles or transverse shifts between the first optical axis and the second optical axis do not interfere with the optical radiation generation.

EFFECT: technical result consists in providing the possibility of the resonator alignment simplification.
