Abstract
The 3rd-order nonlinear optical susceptibility X(3) and the response time of the light-transducing biomolecule bacteriorhodopsin were measured with the four-wave mixing technique and a picosecond frequency-doubled Nd: YAG laser (532 nm). TheX 3) and the response time measured are 10-9 esu and 20 ps, respectively. The possible mechanism for generating the 3rd-order nonlinear optical susceptibility X(3) and response time were discussed.
