Tunable VRM Unstable Resonator Ti∶Al2O3 Laser
【摘要】 将变反射率镜 (VRM)非稳腔成功地应用于可调谐Ti∶Al2 O3 激光器 ,有效地提高了Ti∶Al2 O3 激光的光束质量 ,并利用LBO晶体作为倍频器获得了 396nm~ 44 0nm的蓝色可调谐激光输出 ,最大输出能量为 2 6mJ ,最高倍频效率为 2 7.2 %。
【Abstract】 The beam quality has been improved efficiently by means of a varied reflectivity mirror (VRM) unstable resonator used in a tunable Ti∶Al 2O 3 laser, and a tunable blue laser from 396 nm~440 nm through second harmonic generation (SHG) by LBO crystal is generated. The highest SHG efficiency of 27.2% and the maximum output energy of 26 mJ have been obtained.
