激光器单频激光二极管端面抽运稳频 lasers single frequency laser diode end-pumped frequency stabilized

摘要

报道了激光二极管(LD)端面抽运的1053 nm全固态连续单频稳频Nd∶YLF环形激光器的设计及实验结果。为克服Nd∶YLF晶体应力裂纹极限小的缺点, 采用了较长的、低掺杂的沿c轴切割的Nd∶YLF晶体。激光器的阈值抽运功率为4.7 W, 当抽运光功率为17.9 W时, 单频输出功率可达4.21 W, 长期功率稳定性为±0.8％(4.75 h), 自由运转频率波动为±10 MHz/min。为了改善激光器的频率稳定性, 利用电子伺服系统将激光器的频率锁定在共焦法布里-珀罗(F-P)腔的共振透射峰上, 锁定后, 激光器的频率波动降低为±1.7 MHz/min。

Abstract

A laser diode end-pumped 1053-nm all solid state continuous wave single frequency Nd∶YLF laser is designed and demonstrated experimentally. In order to overcome the low fracture limit, a long and low concentration Nd∶YLF is used in the experiment. The threshold power of the laser is 4.7 W and the single frequency output power is 4.21 W at pump power of 17.9 W. The long term power fluctuation is less than ±0.8％ (4.75 h) and the free running frequency stability is ±10 MHz/min. To improve the frequency stability, the laser is locked to a Fabry-Perot cavity resonance, then the measured frequency stability is less than ±1.7 MHz/min.
