Abstract
Fabrication and laser operation of proton-implanted Ti:sapphire buried channel waveguides is reported for the first time to our knowledge. Without any postimplantation annealing of the structures, continuous laser operation near was demonstrated at room temperature at an absorbed pump power threshold of . Single-transverse-mode laser emission was observed with measured beam propagation factors and of 1.5 and 1.2, respectively. An output power of for pump power was obtained with an output coupler of 4.6% transmission at the signal wavelength. Higher output powers were measured in waveguides with larger cross sections exhibiting multimode laser emission.
