Abstract

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.

摘要

大尺寸高质量的磷酸钛氧钾（KTP）晶体是通过高温溶液法（助熔剂法）生长而成。这些晶体对于1.064微米波长的光，其激光损伤阈值经测量为3至3.5吉瓦/平方厘米；对于0.532微米波长的光，其激光损伤阈值为2.5至3吉瓦/平方厘米。这些晶体的损伤阈值和二次谐波产生转换效率分别与水热法生长的KTP晶体相当及更高。
