Abstract

We fabricated waveguides in Pr:SrAl12O19 crystals by direct femtosecond laser writing. The propagation losses were calculated to be as low as 0.16dB/cm at a wavelength of 633nm. Laser oscillation in a diode-pumped waveguide at a wavelength of 643.5nm was realized. The output power of the waveguide laser was 28.1mW at a slope efficiency of 8%.
