Transparent ceramics have attracted great interests recently for their favorable advantages over traditional single crystals, such as large size, high concentration, low cost, easy fabrication as well as flexible geometry. Therefore, it's significant for the development of high-power, high-frequency and narrow-pulse width laser to investigate new laser geometry using the superior properties of transparent ceramics。.This project will develop a multi-chip active mirror with monolithic transparent ceramic Laser geometry using the advantages of the high doping, complex functional structures of transparent ceramics. In the structure, the gain medium layers are distributed in specific position in undoped substrate. Laser injected through the incident window into transparent ceramics, and total internal reflection occurs in different internal surfaces, and meanwhile the injected laser was amplified on the gain layer. This geometry has high energy-storage, good thermal performance and steady mechanical structure, which can be used to achieve high-power and high-beam quality laser output..The investigation of multi-chip active mirror with monolithic transparent ceramic laser will promote the development of strategic advanced electronic materials and it has broad application prospects in the fields of advanced manufacturing, laser medical treatment, laser communication and national defense.
