Year: 2024

Type: article

Abstract: In this Letter we report the near infrared operation of a femtosecond-laser-written diode-pumped Pr:LiLuF 4 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.
