Abstract

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.

飞秒激光写入 Pr:LiLuF4 波导的近红外二极管泵浦激光器

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。

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
