摘要
报道了一台线性偏振输出、波长为1 341.4 nm、采用激光二极管(LD)连续侧面泵浦的Nd:YAP激光器。通过分析Nd:YAP晶体的能级结构和跃迁特点,显示了Nd:YAP晶体作为1.3μm波段激光器的工作物质的优点。实验对比了不同透过率的输出耦合镜片的输出功率。最终以透过率为6.5%的输出耦合镜片,在555 W的LD泵浦功率下获得了121 W的平行于晶体c轴线性偏振(c偏振)的1 341.4 nm激光输出,光-光转化效率21.8%,斜率效率为41%;并且在c偏振激光失稳后成功获得了平行于a轴的线性偏振(a偏振)的1 339.2 nm激光。
A high-power linearly polarized CW diode-side-pumped Nd：YAIO3 （Nd：YAP） laser oscillating at 1 341.4 nm was reported. By analyzing the level structure and characteristics of transition in Nd：YAP crystal, the advantages of Nd： YAP crystal as a kind of working matter medium of 1.3 μm laser were displayed. Different output couplers for the laser were studied by experiment. Finally, a c-axis polarized laser with an output power as high as 121 W at 1 341.4 nm was obtained with a coupler transmittance of 6.5% at the maximum pumping power of 555 W. The beam quality factor was 34, the optical-optical efficiency was 21.8% and the optical slope efficiency was 41%. The a-axis polarized laser at 1 339.2 nm was also successfully obtained at the caxis polarized laser being instable.
