高功率平板波导激光器进展

详细介绍了平板波导二极管(LD)抽运高功率同体激光器的进展，分析了系统的优点和潜在的风险。具体讨论了接近式LD耦合方式、双包层波导结构和非稳腔的使用，以及梯形结构波导、集成被动调Q设计。激光介质包括Yb^3 ，Nd^3 和Tm^3 掺杂的YAG晶体材料。具有单片紧凑波导结构的激光器可以获得超过10W的激光输出，获得近衍射极限的激光束。将来可以实现100W以上的激光输出并在单片器件内集成更多的功能。

Advancement of High Power Planar Waveguide Lasers

The advancement of high power solid state lasers based on planar waveguide laser pumping is introduced in detail. The advantages and the potential risks are analysed. Proximity LD coupling, doubly-clad waveguide configuration, the use of nonstable cavity, the trapezoidal structure waveguide, and passive integrated Q-switching design are discussed. The laser media includes Yb3+, Nd3+ and Tm3+ doped YAG materials. 10 W and more near diffraction-limited laser output can be obtained from lasers with compact waveguides of monolithic structure. 100 W laser output will be possible and even more functions can be integrated into a monolithic device in the future.
