Abstract

Nonlinear optical properties of oriented purple membrane films (OPMF) were investigated by second harmonic generation from picosecond pulses at 860 nm. A second order nonlinear optical coefficient dejj 1. 05 W109 esu was observed. We propose the use of this nonlinearity for measurement of ultrafast photoelectric response in OPMF after the excitation of bacteriorhodopsin by ultrashort light pulses. 1.
