摘要
用KNbO_3和KTP两种晶体对ps的Nd:YAG激光倍频,从理论分析和实验上进行了倍频效率比较,用3mm的KNbO_3和4.5mm的KTP得到倍频效率分别为52％和45.4％。证明KNbO_3倍频效率高于KTP,但由于KNbO_3的温度特性使得应用上不如KTP方便。
The SHG of the picosecond Nd:YAG laser was studied experiment ally and theor etically using nonlinear optical crystals KNbO3 and KTP. The SHG energy conversion efficiencies of 52% and 45.4% wera obtained using 3mm-long KNbO3 and 4.5 mm-long KTP respestively. It proves that the SHG with KNbO3 is more effective than that of KTP. Due to the temperature characteristic of KNbO3, however, it is unconvenient for application in comparison with KTP.
