Problems solved by technology
[0003] The important parameters to measure the chip amplifier are optical aperture, small signal gain coefficient, gain uniformity, energy storage efficiency, etc., especially for the chip amplifier, the above-mentioned various high-power laser drivers, the small size of the chip laser amplifier The signal gain coefficient is low and the gain uniformity is poor
To solve this kind of problem, the existing technology generally increases the number of xenon lamps and increases the pumping intensity in order to achieve a larger small-signal gain coefficient. However, the gain uniformity at this time is poor, resulting in serious wavefront distortion, which affects the system. The practicability and stability of the system, while the overall efficiency of the system is also low

Description
technical field [0001] The invention relates to the technical field of high-power solid-state lasers, in particular to a chip laser amplifier. Background technique [0002] During the development of high-power solid-state laser drivers for more than 30 years, laser driver technology has developed rapidly, especially under the stimulation of laser inertial confinement fusion technology. A lot of research has been done on this level of ultra-high power laser drivers, such as the Livermore Laboratory in the United States, the Rimel Laboratory in France, and the Laser Engineering Center of Osaka University in Japan. Among them, the high-power laser driver developed by Livermore Laboratory in the United States represents the highest level in the world. Since the 1970s, solid-state laser systems such as Janus, Argus, Shiva, Nova and NIF have been built successively. Huge development. In these laser drivers, a very important module is the chip laser amplifier, which mainly solves...
