提出了采用迈克尔逊干涉复合腔技术进行两路固体激光器相干合成的实验方案。该方案利用双光束干涉时的相干相长和相干相消特性
结合谐振腔自身的增益损耗原理来实现两激光器的被动式相干合成。理论分析了该技术的锁相机理
并在实验中实现了两路脉冲固体激光器的相位锁定
获得了单脉冲能量300 mJ的相干合成激光输出
合束效率约为80%。实验表明
采用提出的复合腔技术实现相干合成具有自选择和自调整的特点
且结构简单、合束效率高
很好地解决了多路激光相干合成时遇到的占空比问题
可以实现多路固体激光器的相干合成。
A coherent combining scheme for two solid state lasers was proposed by using Michelson cavity technique. Based on constructive interference and destructive interference properties of two beam interferences
this scheme implemented the passive coherent combination of two lasers in consideration of the gain loss of a cavity. The phase-locking principle was analyzed in detail and the phase-lockings of two individual pulsed solid state lasers were experimentally demonstrated.Finally
the coherent combination output energy of 300 mJ/pulse was obtained
and its combination efficiency was 80%. These results show that the coherent combining technique proposed in this paper is characterized by self-choosing and self-adjusting and can offer a high combination efficiency.The technique can also be used in multi-beam solid laser coherence combination
for it solves the problem on the duty ra- tio in coherent combination.
