摘　　要：报道了分别使用水热法和熔盐法的KTP对Nd:GdVO4晶体倍频绿光的对比研究。通过理论分析和计算两种方法的KTP倍频效率与温度的关系,在实验中,当抽运功率为6.11W时,水热法与熔盐法KTP倍频的Nd:GdVO4激光器输出绿光功率分别为0.7W、0.63W,光-光转换效率为11.5%、10.3%,并分析了转换效率不同以及偏低的原因。The contrastive study of green laser with LD-pumped Nd：GdVO4 crystal , hydrothermal and flux grown KTP intracavity frequency doubling is first reported. By programmed and computed the relation of doubled efficiency and temperature of two KTP, with 6.11W pumped power, TEM00 mode green laser at 532 nm of 0.7 W and 0.63 W, the light-light conversion efficiency are 11.5% and 10.3%. The causes for the difference and lowness of conversion efficiency are analyzed. From the result of the experiment, some different performances of hydro- thermal and flux grown KTP are gotten, these results can offer some references to next researches.
