| 摘 要： | 通过锁定多模块输出激光相位实现激光功率扩展的相干合成技术是获得高能高光束质量光源的有效途径.本文分析了相互注入锁定相干合成的机理及其对激光器相干性的影响,利用偏振元件将两路独立的Nd:YAG激光器关联起来,解决了耦合过程中的损耗问题,实现了两路激光器的相互注入锁定,获得了总功率4.4W的部分相干激光输出,长曝光结果表明远场光斑峰值功率密度提高了1.4倍,对利用相干合成技术实现高能固体激光器技术进行了初步探索.

| Abstract: | Coherent beam combining(CBC),used in scaling power by phase-locking multi-lasers,is an efficient approach to achieve high brightness laser.Based on this approach,the current study analyzed the mechanism of mutual injection-locking and its influence to the laser coherence.Furthermore,two independent Nd:YAG lasers were associated with each other by polarized elements,achieving the mutual-injection-locking of two lasers.Coherent laser power reached 4.4W and the peak intensity rosed up to 1.4 factor.Thus,this research made an tentative exploration of the high power coherent beam combining laser. |
