Abstract：Nowadays, high power solid-state laser is kind of laser which is of reliable operation and fully maturity, and the devices sold in the market are running reliably and operated conveniently. Therefore, high power solid-state laser has been widely used in perse fields. Since 1960, scientists began to use ruby as laser medium, and later, various media materials were used in laser, such as Nd:YAG, Nd glass and Alexandrite. Most laser system used for industrial processing of materials used Nd:YAG, and almost only small parts of the system used Wd glass. This paper includes: We first briefly introduced the research background of the high power solid laser, and then discussed the structure and principle, advantages, application and the development tendency of the four kinds of lasers including DPSSL, SSHCL, double clad fiber lasers, and COIL. We also show the progress of high power solid state lasers in terms of lifetime and power output. In the end, we introduced the application of the above four high power lasers in industry, medicine and military, which has profound meaning and significance in every field.

Keywords: Diode pumped solid-state laser, Heat capacity laser, Double clad fiber laser, Non solid chemical oxygen iodine laser, Cooling technology
