Abstract A GdxY1-xCa4O(BO3)3 (GdxY1-xCOB) crystal, which belongs to rare-earth calcium oxyborate family, is used for non-critical phase-matching of visible and ultraviolet (UV) light. We employ 2.8-MeV He+ ions to form optical waveguides in the Gd0.275Y0.725COB crystal at room temperature. The doses are varied from 1.5 × 1016ions/cm2 to 5 × 1016ions/cm2. A model 2010 prism coupler is used to measure the modes in Gd0.275Y0.725COB waveguides formed by MeV He+ ion implantation. The refractive index profile is fitted based on the reflectivity calculation method. The shape of refractive index profile is compared with one of nuclear energy loss obtained by TRIM’98 simulation.
