Abstract

Phenosafranin is shown to have an intense triplet-triplet absorption band in the 600 - 850 nm spectral region. This absorption was investigated in samples prepared by doping PVA films or by doping solgel glasses. The resulting optical samples are shown to have an intensity depending absorption upon pumping by an Ar+ laser. This nonlinear optical absorption can be utilized for construction of optical bistable devices, such as spatial light modulators. In addition, this absorption is manifested in photorefractivity of the samples.
