Abstract: Surface channel waveguides (WGs) based on a half-ring (40-60-mu m-diameter) depressed-index cladding (type HI) geometry are fabricated in monoclinic Tm3+:MgWO4 by femtosecond (fs) laser writing at a repetition rate of 1 kHz. The WGs are characterized by con focal laser microscopy and mu-Raman spectroscopy. A Tm3+:MgWO4 WG laser generates 320 mW at similar to 2.02 mu m with a slope efficiency of 64.4%. The WG emits a transverse single-mode and linear polarization (E parallel to N-m). A remarkable low loss of < 0.1 dB/cm is measured for the WG. Vibronic laser emission at similar to 2.08 mu m is also achieved. (C) 2020 Optical Society of America
