Abstract

We have demonstrated 5.5 W of average power in the TEM₀₀ mode with a slope efficiency of 30% from a copper-vapor-laser-pumped Ti:Al₂O₃ laser at a pulse repetition rate of 6.5 kHz and a pump power of 21.4 W. The laser crystal was longitudinally pumped through both end faces. With a three-plate birefringent tuner the laser bandwidth was reduced to less than 0.25 nm and was tunable from 750 to 825 nm.
