实验证明了一种紧凑的全固态532 nm半高斯激光束（SGB）源，该源基于1064 nm激光器和横向变化的周期性极化LiTaO3 （TPPLT）晶体作为激光束整形器和非线性频率转换器。我们利用所设计的TPPLT晶体，通过一次二次谐波产生，获得了质量为QSGB=1:17.5的532nm整齐的SGB。讨论了生成的SGB质量与设计的TPPLT参数的关系，以及整洁SGB的潜在应用。
We experimentally demonstrate a compact, all-solid-state 532 nm semi-Gaussian laser beam (SGB) source based on a 1064 nm laser and a transversely varying periodically-poled LiTaO3 (TPPLT) crystal as the laser beam shaper as well as the nonlinear frequency converter. We have used the designed TPPLT crystal to obtain a neat 532nm SGB with the quality of QSGB=1:17.5 by a single-pass second harmonic generation. The dependence of the generated SGB quality on the designed TPPLT parameter and the potential applications of the neat SGB are also discussed.
