Problems solved by technology

The currently used laser amplifier has a low gain due to its poor heat dissipation effect. In addition, when the existing laser amplifier is used, it needs to achieve total internal reflection on the pump surface, which causes stress deformation on the pump surface. so that the beam quality deteriorates

Description

technical field [0001] The invention relates to a laser amplifier. Background technique [0002] A laser amplifier refers to a device that uses stimulated radiation of light to amplify the energy (power) of light. By using a laser amplifier, it is possible to obtain high laser energy or power while maintaining the quality of the laser (including pulse width, line width, polarization characteristics, etc.). It is often used in high-power laser systems in major technologies such as controllable nuclear fusion, nuclear explosion simulation, and ultra-long laser ranging. The currently used laser amplifier has a low gain due to its poor heat dissipation effect. In addition, when the existing laser amplifier is used, it needs to achieve total internal reflection on the pump surface, which causes stress deformation on the pump surface. As a result, the beam quality deteriorates. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating ...
