【摘要】 为了研究Nd:YAP晶体在LD端面抽运中的1341.4nm激光输出特性,采用理论计算和实验测量了实验系统的热焦距,对比了平平腔和平凹腔激光输出结果。采用输出耦合率为T=2.4%的平凹腔和输出耦合率为T=2.6%的平平腔,分别得到了3.15W和2.86W的1341.4nm线偏振激光输出,对应斜效率分别为18.4%和17.5%。结果表明,Nd:YAP作为1.3μm波段激光晶体具有潜在的优点。更多还原

【Abstract】 In order to study the output characteristics of diode-end-pumped Nd: YAP laser operating at 1341. 4nm,the thermal focal lengths of end-pumped Nd:YAP laser were calculated and measured, and the output results of lasers with plane- plane and plano-concave resonators were compared respectively. Making use of plane-concave resonator with the coupler transmission of 2. 4% and plane-plane cavity with the coupler transmission of 2. 6% ,3. 15W and 2. 86W linearly polarized laser radiation at 1341.4 nm were obtained,respectively,corresponding optical slope efficiency of 18.4% and 17. 5% . The results show that Nd:YAP laser crystal owns the potential advantages on 1.3μm laser.更多还原
