摘要
报道了超短脉冲激光和单色激光分别通过锯齿光阑或圆孔先阑整形系统的传输特性及其在高能激光系统中的应用。和超短脉冲激光通过直接利用锯齿光阑便能得到近场光强分布相对均匀的超高斯光束相比,利用圆孔光阑对单色激光进行整形,却必须和空间滤波器相结合使用才能得到相应结果。
This paper mentions the transmission features of the ultra-short pulsed-laser and monochromatic laser while they arc respectively passing through the circular or serrated apertures shaping system, but also presents their application in high energy laser system. Just using serrated aperture we can get ultra-gauss light beams of near-field uniform intensity distribution from ultra-short pulse laser. By contrast when using circular apertures to shape CW laser, we must combine it with spatial filter to get the same effect.
