摘　　要：实验研究了离子掺杂浓度以及输出镜透射率对Tm:YAP激光器输出性能的影响。晶体沿c轴切割,尺寸为3mm×3mm×5mm,在输出镜透射率为5%的条件下研究了掺杂离子数分数分别为3%、4%和5%三种情况的激光性能。结果表明,掺杂离子数分数为4%的Tm:YAP晶体输出性能最好,当抽运功率为24.8 W时,连续输出功率最大为7.5W,斜率效率为48.8%。使用掺杂离子数分数为4%的Tm:YAP,研究了2%,5%和10%三种输出透射率情况下激光器的输出性能。结果表明,当透射率为5%时斜率效率最高。The influence of thulium ion concentration and output-mirror transmittance on Tm： YAP crystal laser output performance is experimentally investigated. Three c-cut crystals in size of 3 mm X 3 ram）〈 5 mm with 3 %, 4 % and 5 % Tm3＋ （ionic-number fraction） are examined with the transmittance of 5 %. Experimental results showed that the best power performance is obtained with the 4 % Tm： YAP crystal. By using 24.8 W incident pump power, a maximum output power of 7.5 W is obtained. The slope efficiency is 48.8 %. Using different output transmittances of 2%, 5% and 10%, we investigate the laser performance with 4% thulium ion. The results show that with the transmittance of 5 %, the highest slope efficiency is obtained.
