本文报道了激光二极管端面抽运的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。为了克服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小时），自由运转频率波动为10 MHz/分钟。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/分钟。
laser diode end-pumped 1053 nm all solid state continuous wave single frequency Nd:YLF laser was designed and demonstrated experimentally. In order to overcome the low fracture limit, a long and low concentration Nd:YLF was 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％ and the free running frequency stability is 10 MHz/min. To improve the frequency stability, the laser was locked to a Fabry–Perot cavity resonance, the measured frequency stability is less than 1.7 MHz/min.
