| 摘 要： | 在激光实际应用中,为了提高系统的利用效率,常常需要将激光器的输出光束整形为特定光强分布光束.基于纯相位液晶空间光调制器的高空间分辨率、实时可编程控制等特性,结合模拟退火算法搭建了一套自适应近场光束整形系统.理论模拟了该系统对于理想高斯光束的近场整形效果,并基于这一闭环系统,对固体激光器输出的近高斯光束进行了近场光束整形...

| Abstract: | In practical applications,it is always necessary to convert the intensity distributions of the laser beams into desired profiles for improving the efficiency.Based on the high spatial resolution and programmable controller of the phase-only liquid crystal spatial light modulator,an adaptive near-field beam shaping system composed of simulated annealing algorithm is built.The feasibility of the system is validated by translating an ideal Gaussian beam into a flattop beam in the near field theoretically.Final... |
