摘要

利用改进的迈克尔逊腔(IMC)，证明了双侧泵浦Nd:YAG激光器的相干结合输出功率为41.5 W。相干结合效率超过80%，光束质量得到明显改善。此外，它还可以直接实现相干组合后的单光束输出。此外，它可以承受环境扰动而不改变光束质量和输出功率。实验证明了利用IMC实现高功率相干组合的有效途径。最后，对大功率IMC相干附加器件的进一步发展进行了详细的讨论。利用IMC相干加法技术可以研制出超高功率(例如100千瓦级)激光系统

High Power Coherent Addition in an Improved Michelson Cavity

The coherent combining with an output power of 41.5 W for two side-pumped Nd:YAG lasers was demonstrated by use of an improved Michelson cavity (IMC). And the coherent combining efficiency exceeded 80% and the beam quality was significantly improved. What is more, it can directly realize a single beam output after coherent combining. Moreover, it can withstand environmental perturbations without alteration in beam quality and output power. The experiment showed an efficient approach for high power coherent combining by use of the IMC. At last, the further development for the high-power IMC coherent addition was discussed in detail. It is possible to develop an ultra-high power (e.g. 100 kW-class) laser system by the IMC coherent addition technique
