Abstract: During the measurement of optical nonlinearities of sample in the thin film by Z-scan technique, ablating makes a hole in the thin film if the incidental laser power is too high, that will produce the error to measurement results.

文摘:用单光束扫描法研究薄膜材料的非线性光学性质时，如果入射样品的激光功率过大，将会烧蚀薄膜而产生孔洞，虽然其归一化透过率曲线类似于没有烧蚀的情况，但与样品的非线性光学性质无关，因而造成测量结果错误。
