利用腔内位相调制改善固体激光器的光束质量
Beam Quality Improvement by Intracavity Phase Modulation in Solid-state Laser
摘要
提出一种新的利用腔内位相调制的方法来改善激光器输出的光束质量.位相调制用铌酸锂(LiNbO3)电光晶体实现,所用激光器为连续氪灯抽运的Nd:YAG激光器.实验结果表明,利用腔内位相调制的方法,可以有效地使多模激光变为具有均匀光强分布的近基模光束.
Abstract
A new method to improve laser beam quality by using intracavity phase modulation is presented. The phase modulation is fulfilled by LiNbO 3 electro optic crystal driven by high voltage. The laser used is CW Nd:YAG solid state laser pumped by Krypton lamps. The experimental results show that intracavity phase modulation can transfer effectively the laser oscillation mode from multi mode to fundamental mode like beam with smooth intensity profile.
