High power all-solid-state laser technology in advanced manufacturing and other industrial processes not only has important applications, but also the weapon one key technology for great performance. This article first describes the status of high power solid state lasers, and introduced Rod lasers, lasers, slice slab laser and Fiber Laser performance features and benefits. Explain the need for the development of high power solid state laser technology and the importance, and then introduces two high power solid state laser technology: heat capacity laser technology and laser coherent synthesis technology. Because laser beams bination of technologies that require high power, high brightness laser beam under a wide range of applications, compared with other synthesis technologies, this technology with simplicity, stability and expansion, this technology has been introduced . Development of solid state laser direction: to high power, high beam quality of high-power device development, and strategic application of high power solid state lasers will be strengthened so as to develop more new technologies. The subject emphasis is placed on the design of high power solid state laser sta
