Study of laser channel waveguides in Nd: YAG crystals obtained by proton implantation

摘要

In this work a study of the effects on the optical properties of channel waveguides in Nd:YAG crystals fabricated with different proton implantations doses is presented. The channel structure was achieved by using an electroformed mask with openings through which the protons were implanted. The optical properties studied included microphotographs, the transversal modal distribution at visible wavelengths, the photoluminescence spectra and the laser emission. The laser performance of the waveguides was obtained in a resonant cavity configuration with mirrors held onto the polished end faces of the waveguides.
