摘要

NdLiP4O12 crystals can be used for low-threshold, miniature laser. A double waveguide structure in a NdLiP4O12 laser crystal formed by ion implantation is for the first time reported. Double waveguide in NdLiP4O12 laser crystal is formed with 2.8 and 1.8MeV He ions to the same dose of 1.5×1016 He ions/cm2. The refractive index distribution of the double waveguide in the NdLiP4O12 laser crystal is given based on the reflectivity calculation method.
