摘要: Wavelength dependence of saturable absorption (SA) and reverse (RSA) zinc phthalocyanine was studied using 10Hz, 8ns pulses from a tunable laser, in the wavelength range 520–686nm, which includes rising edge Q band electronic spectrum. The nonlinear response is dependent switching RSA to SA has been observed as excitation changes low window region higher regime near band. again back when we further move over infrared region. Values imaginary part third order susceptibility are calculated for various wavelengths this range. This study important identifying spectral material acts based optical limiter.
