Abstract

We report on the waveguide formation in the Nd:Li6Y(BO3)3 laser crystal by oxygen or silicon ion implantation, respectively, and how the waveguide structure effectively supports the fundamental mode in the visible and near-infrared telecommunication band. Compared with Si-ion, the waveguide produced by O-ion has a larger effective refractive index of fundamental mode and lower propagation loss, which shows that peak position of implanted ion nuclear energy loss has a significant impact on waveguide features. The investigation of the photoluminescence and Raman spectra demonstrates that the Nd3+ luminescence feature and crystal structure of the waveguide active region do not change significantly and gain good preservation after ion implantation.
