摘要: Photo-induced enhancement processes of the third-order optical nonlinearity were observed in azobenzene solution under a 3Ops pulse pumping at 532 nm. Weinvestigated the time evolotion of the enhancement and found that it was mainly due to thc population of the first excited stale. By theoretical simulation of the enhancement processes, the values of the hyperpolarizabilities of the sample-molecules at ground state and at excited state, γg and γs1 were determined to be 1.11×10-33 esu and 7.40×10-33, respectively.
