Abstract
Potassium titanyl phosphate (KTiOPO4 or KTP) was implanted by 3.0 MeV Er ions to a dose of 7.5 x 10(14) ions cm(-2) at room temperature. The damage in the as-implanted KTiOPO4 was studied by Rutherford backscat tering channeling. Photoluminescence (PL) measurement was performed at 10 K; the Er-implanted KTiOPO4 sample was annealed at 750 degrees C f or 20 min in a N-2 atmosphere and then implanted by 2.8 MeV He ions to a dose of 1.5 x 10(16) ions cm(-2) at room temperature. The dark mode s were measured by the prism coupling method. 14 dark modes were obser ved in KTiOPO4. The refractive index profile in the KTiPOP4 waveguide was theoretically analyzed, The result shows that the shape of the ref ractive index profile is similar to one of the nuclear energy loss dis tribution.
