Abstract: We have produced planar optical waveguides having a crystalline CaF₂–YF₃–NdF₃ mixed yttrofluorite core and two reflective claddings in order to improve waveguide excitation efficiency. Under diode pumping, lasing has been achieved at a wavelength of 1064 nm with a slope efficiency near 15%.

Keywords: mixed fluoride crystals, double-clad planar optical waveguides, lasing.
