Laser damage threshold of KTiOPO(4).
Laser damage thresholds are reported for two unpoled and one poled KTiOPO(4) crystals under similar experimental conditions. For the TEM(00) mode of a Nd:YAG laser, the fluence and power density values for the unpoled crystals (23-33 J/cm(2) and 2-3 GW/cm(2), respectively) were higher than for the poled crystal (10-17 J/cm(2) and 0.8-1.3 GW/cm(2)). Even for a poled KTP, the damage threshold is higher than potassium dihydrogen phosphate or KDP (6-9 J/cm(2)).
