Abstract
Studies of high optical power density propagation in Ti‐diffused LiTaO3 waveguides are described. Optical damage at room temperature involving ’’blow‐out’’ of the central output spot into the m line and clean‐up phenomena have been observed. Studies at elevated temperature (≈150 °C) indicate that self‐annealing of the damage allows these structures to sustain optical power densities up to 11 kW/cm2 at 5145 Å without damage and power saturation. Use of high‐purity LiTaO3 is required if room‐temperature operation at these high optical power densities is to be achieved.Keywords
