Laser damage tests of large flux-grown KTiOPO(4) crystals.
Large high-quality KTP crystals are grown from a high-temperature solution (the flux method). The laser damage threshold for these crystals is measured to be 3-3.5 GW/cm(2) for 1.064-microm light and 2.5-3 GW/cm(2) for 0.532-microm light. The damage thresholds and second-harmonic-generation conversion efficiency are comparable with and higher than those for hydrothermally grown KTP, respectively.
