摘要

通过在特定的激光腔内放置空间光调制器(SLM),可以实现激光束的空间分布控制。SLM的开放像素决定了生成模式的配置(这种SLM可以称为“驱动镜像”)。早期的工作[1,2]已经表明,在q开关操作下,可以获得几焦耳的固态扫描激光器输出能级,并且可以实现高速扫描。同时,解决了单计算机驱动SLM单元对激光束进行二维随机寻址的问题。

DPSSL with 2D Intracavity Beam Scanning Using Liquid Crystal Spatial Light Modulators
The laser beam spatial distribution control can be obtained by the placing a Spatial Light Modulator (SLM) inside a special laser cavity. The opened pixels of the SLM determine the generating modes configuration (such SLM can be called "driven mirror"). The earlier works [1,2] has shown the possibility to obtain output energy level of solid-state scanning laser of several Joules on Q-switch operation, and high speed of scanning. At the same time, 2D random-addressing of laser beam by the single computer-driven SLM unit was the problem unsolved.
