Abstract

In this work we present the laser performance of channel waveguides which operate at 1064 nm at room temperature. These channels were made on Nd: YAG crystal by proton implantation with different widths (10, 15 and 20 μm) forming sets of 10 waveguides which are separated by a distance of 215 μm. The results shown are transversal mode distribution, propagation losses, absorption and luminescence spectra and laser emission characteristics such as pump power threshold and slope efficiency. The spectroscopic characterization indicates that the optical properties of the waveguide in comparison with the bulk material are preserved after the implantation process and that this is a potential technique to develop compact and efficient lasers.
