Abstract

Laser oscillation at a wavelength of 1520 nm was obtained in an Er:Yb:YAl(3)(BO(3))(4) crystal end pumped by a 970 nm diode laser. Under the absorbed pump power of 14.6 W, quasi-continuous-wave output powers of 1.1 W with slope efficiency of 13% and 0.8 W with slope efficiency of 11% were achieved in hemispherical and plano-plano cavities, respectively. The laser spectra were recorded for both cavities. The influence of the thermal load in the crystal on the 1520 nm laser oscillation was analyzed.

摘要

在由970nm二极管激光器端面泵浦的掺铒镱铝硼酸盐（Er:Yb:YAl(3)(BO(3))(4)）晶体中实现了波长为1520nm的激光振荡。在14.6W的吸收泵浦功率下，在半球形和平平腔中分别获得了斜率效率为13%的1.1W准连续波输出功率和斜率效率为11%的0.8W准连续波输出功率。记录了两个腔的激光光谱。分析了晶体中的热负载对1520nm激光振荡的影响。
