Abstract

The invention discloses a laser gain structure and a laser. The laser gain structure includes gain tubes for increasing light beam energy under the action of a pump source. A first fluid passage is formed in each gain tube. The outside of each gain tube is wrapped in a sealing tube. A gap exists between each sealing tube and the corresponding gain tube. A second fluid passage is formed in each gap. The first fluid passages and the second fluid passages are used for passing a cooling medium so as to make the temperature of the outside of the gain tubes and the inside of the gain tubes tend to coincide. The outside of each gain tube is also wrapped in a reflective surface for total reflection of light beams. When the laser gain structure of the embodiments is used for increasing the laser energy, diffraction loss of the laser beams in a propagation process can be reduced. The gain tubes are better in cooling effect and higher in energy storage so as to achieve output with higher energy.

Description

technical field [0001] The present application relates to the field of laser technology, in particular, to a laser gain structure and a laser. Background technique [0002] High-power lasers are widely used in national defense, industry, scientific research and other fields. The laser gain module is the core unit of the high average power solid-state laser, and the laser gain module with excellent performance is the guarantee for realizing high-efficiency and high-beam-quality laser. [0003] In prior art, please refer to figure 1 , the commonly used laser gain structure is a slab made of gain medium. In this gain structure, the main laser is transmitted in a zigzag optical path. In this gain structure, due to the non-uniform heat of the slab, at the edge of the slab, the temperature of the center of the slab is not consistent with that of the edge, and it is easier to produce edge effects, that is, at the edge of the slab, the beam wavefront and Inconsistency at the cent...
