千瓦级3倍衍射极限的高功率热容激光器
Kilowatt High Power Heat Capacity Laser with 3 Times Diffraction Limit
摘要
开展了热容激光器光束质量控制研究，进行了耦合系统的优化设计，采用了透镜压缩结合波导匀化的设计思想，使抽运均匀性提高到90%的水平；进一步建立了有源非稳腔的理论分析模型，针对热容激光器的抽运条件开展了非稳腔的优化设计，实验结果表明实现了2.7倍衍射极限的千瓦级热容激光输出。
Abstract
In order to get uniform gain distribution to reduce thermal effect, coupling system was optimistically designed by means of lens compression and wave-guide equality to improve the uniform of gain distribution to 90%. The numerical simulation module on unsteady resonator was established to analyze the change of the beam quality with time in heat capacity laser. The experimental results show that kilowatt level of burst power with 2.7 times diffraction limit is gotten.
