摘要

在这封信中，我们报告了飞秒激光写入二极管泵浦 Pr:LiLuF4 波导激光器的近红外工作情况。通过采用传播损耗低至 0.19 dB/cm 的圆形凹陷包层波导，我们演示了 914 nm 波长的激光，最大输出功率为 140 mW，斜率效率为 24%。此外，我们还证明了波导器件在 894 纳米、922 纳米和 933 纳米波段发生激光的可能性。据作者所知，这是首次演示基于镨的波导激光器在这一光谱区域工作。

Near infrared diode-pumped lasing of femtosecond-laser-written Pr:LiLuF4 waveguide

In this Letter we report the near infrared operation of a femtosecond-laser-written diode-pumped Pr:LiLuF₄ waveguide laser. By employing a circular depressed-cladding waveguide with propagation losses as low as 0.19 dB/cm, we demonstrated lasing at 914 nm, with a maximum output power of 140 mW and a slope efficiency of 24%. Moreover, we demonstrated the possibility of lasing in a waveguide device at 894 nm, 922 nm and 933 nm. To the authors knowledge, this is the first demonstration of a Pr-based waveguide laser operating in this spectral region.
