摘要：
We report the pump-probe measurements of nonlinear refractive index changes in photochromic bacteriorliodopsin films. The photoinduced absorption is caused by pump beam at 532 urn and the accompanying refractive index changes are studied using a probe beam at 633 urn. The proposed technique is based oil a convenient and accurate determination of optical path difference using digital interferometry-based local fringe shift. The results are presented for the wild-type as well as genetically modified D96N variant of the bacteriorhodopsin.
