Abstract
Ridge low loss (0.16±0.02 dB/cm) waveguides were fabricated in Pr,Gd:LiYF4 epitaxial layers by precision diamond-saw dicing. The red waveguide laser generated 504 mW at 639.7 nm with a slope efficiency of 57.8%, a linear polarization and a laser threshold of 34 mW. Laser operation in the orange and deep red was also demonstrated.
