Problems solved by technology

[0003] The object of the present invention is to provide a laser gain medium cooling and clamping device for thin-sheet lasers, so as to overcome the hard mechanical damage caused by uneven clamping force of the thin-sheet laser medium and the thermal effect caused by the failure of effective cooling due to insufficient clamping. Thin sheet laser can obtain uniform clamping and good cooling effect, which is suitable for the development of high brightness all solid-state thin sheet laser

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawings and implementation.

[0019] see first figure 1 , figure 1 It is a structural schematic diagram of the laser medium cooling device of the thin-sheet laser of the present invention. As can be seen from the figure, the laser medium cooling device of the sheet laser of the present invention comprises a semiconductor thermoelectric cooling chip 10, a laser gain medium 8, a white gem window plate 7 and a clamp 6, which is characterized in that the clamp 6 is a flat-bottomed disk-shaped There is a red copper clamp 6 with an external thread in the mouth of the sliding guide rail 5 for the sliding of the white gemstone window plate 7, and the red copper clamp 6 is fixed on the semiconductor thermoelectric cooling sheet 10 by the fixing screw 4. There is also a thin metal indium layer 9 on the inner bottom of the fixture 6, and the laser gain medium 8, the white sapphire window pl...

Abstract

A laser medium refrigerator of a film laser characterizes that the edge of a disk like sliding guide way providing slide of a white jewel window panel has a red copper clamp with outer screw thread to be fixed on a cooling plate by screws, the internal base of the red copper clamp has a thin In layer orderly set with said laser gain medium, the white jewel window panel and a micro-ring like sealed hydraulic pressure bag, then the ring inner screw thread with a cover presses said outer screw thread of the copper clamp to apply a force on the hydraulic bag connected with a meter externally.

Description

technical field [0001] The invention relates to a solid-state laser, in particular to a high-brightness all-solid-state thin-plate laser that is end-pumped to a temperature-sensitive Yb-doped active ion laser gain medium. Background technique [0002] Diode-pumped solid-state lasers (DPSSL) have four main configurations for the development of high average power: end-pumped rods, side-pumped rods, side-pumped slabs, and surface-pumped and edge-pumped sheet lasers. It has been demonstrated as the most promising high-brightness laser system by research in recent years. The output direction of its laser beam is perpendicular to the thermal gradient of the laser medium. Theoretically, it can overcome the contradiction between high power and high brightness that traditional solid-state lasers cannot overcome. The quality of the output beam is close to the diffraction limit, and the output power can be developed into an average power. The potential of tens of kilowatts or even hun...
