基于全反射长程泵浦吸收和激光增益振荡的小型高效高可靠激光器研究

Novel laser is an important research direction in the laser technology. The miniaturization, efficiency and reliability of lasers have restricted the development and application of novel lasers, these bottlenecks should be solved imminently. The laser features of miniaturization, high efficiency and high reliability have many basic issues including the pump light coupling, energy absorption, and laser gain extract and loss suppression. The theory and method of total reflected long range pump absorption and laser gain oscillation is expected to improve the miniaturization, efficiency and reliability of lasers. This project is arranged to research the key theory and method of total reflected laser.1) by research the theory and method of total reflected long range pump absorption, get the regular of pump light absorption against the pump light propagating path and the spectral drift which is induced by the temperature drift, establish a pump light model to realize the goal of minimizing the temperature control system and decreasing the temperature control power.2) by research the theory and method of total reflected laser gain oscillation, construct a special laser resonator integration on the laser gain media. Laser using this integrated component may be much more miniature and reliable. The research of this project can provide theoretical and technical support for the development of minimized, high efficient, and high reliable laser. This project is worth of investigation.
