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。激光器的闽值抽运功率为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。
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.
