Abstract

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)).

摘要

报道了在相似实验条件下两种未极化和一种极化的磷酸钛氧钾（KTiOPO₄）晶体的激光损伤阈值。对于Nd:YAG激光器的TEM(00)模式，未极化晶体的能量密度和功率密度值（分别为23 - 33 J/cm²和2 - 3 GW/cm²）高于极化晶体（10 - 17 J/cm²和0.8 - 1.3 GW/cm²）。即使对于极化的磷酸钛氧钾晶体，其损伤阈值也高于磷酸二氢钾或KDP（6 - 9 J/cm²）。
