Laser gain component and laser device

Abstract

The invention discloses a laser gain component and a laser device. The laser gain component comprises a pumping source and a gain pipe, and laser beam energy is improved by the gain pipe under the action of the pumping source. A first fluid channel is formed in the gain pipe, the gain pipe comprises a gain straight pipe and two tubular end caps arranged at two ends of the gain straight pipe, the first fluid channel penetrates the gain straight pipe and the two tubular end caps, the tubular end caps are in a shape of a boss, a first sealing pipe wraps the outer side of the gain straight pipe and is separated from the gain straight pipe to form a second fluid channel, and the first fluid channel and the second fluid channel are used for passing cooling media, so that the outer temperature ofthe gain straight pipe is consistent with the inner temperature of the gain straight pipe. When lasers are transmitted by the laser gain component and the laser device, laser beam quality and energycan be effectively improved, and the energy storage capability of the gain pipe can be greatly improved.

Description

technical field [0001] The present application relates to the field of laser technology, in particular, to a laser gain component and a laser. Background technique [0002] High-power lasers are widely used in national defense, industry, scientific research and other fields. The laser gain component is the core unit of the high average power solid-state laser, and the laser gain component with excellent performance is the guarantee for achieving high efficiency and high laser beam quality. [0003] In the prior art, a commonly used laser gain component includes a slab composed of a gain medium. In this gain component, laser light is transmitted in the slab through a zigzag optical path. The inventor found through research that because the heat of the slats is not uniform, and at the edge of the slats, because the temperature at the edges of the slats is inconsistent with that at the non-edges, it is easier to produce edge effects, that is, at the edges of the slats, the las...

Problems solved by technology

The inventor found through research that because the heat of the slats is not uniform, and at the edge of the slats, because the temperature at the edges of the slats is inconsistent with that at the non-edges, it is easier to produce edge effects, that is, at the edges of the slats, the laser beam The wavefront does not coincide with the center, which affects the quality of the final output laser beam
