Abstract

The 3rd order nonlinear susceptibility χ (3) and response time of the azobenzene π conjugated derivatives are measured with the four wave mixing technique and picosecond frequency doubled Nd∶YAG laser (532 nm). The measured χ (3) and response time are 10 -9 esu and 20 ps, respectively. The mechanism of transient grating effect and response time are discussed.
