Abstract
Nonlinear optical properties of multilayer Langmuir-Blodgett films (LBF) of bacteriorhodopsin (bR) were studied experimentally. The samples were deposited in Y- and Z-configurations (Z-type bR films up to 50 layers were manufactured at first). The method of second-harmonic generation and the Z-scan technique were used in order to evaluate the elements of susceptibility second-order tensor and to determine the sign and approximate magnitude of refractive index nonlinear part for the samples studied.
