摘要
用腔内倍频方法测量无源腔内晶体吸收和散射共同作用带来的损耗，其特点是响应时间很短，约１００ｎｓ，并具有很高的灵敏度（约１０－４），可望应用于高功率激光照射下非线性光学晶体无损损伤以及快速损伤的研究。将测量ＫＤＰ类晶体的损耗结果与文献资料作了比较。
A special designation is reported to measure the loss together of absorption and deflectionin NLO crystals in the cavity. The method has characters of high sensitivity to about 10-4 and fast responsetime up to 100 nanoseconds. We consider it extensible to be applied in the studies of nondestructive and quickdestructive detection of NLO crystals related to the irradiation of high peek power laser. The results of KTP.KDP.KD P crystals in our experiment and also the comparison to others is shown.
