摘要
详细介绍了平板波导二极管(LD)抽运高功率固体激光器的进展,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Yb3+,Nd3+和Tm3+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。
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.
