Abstract: We have studied the nonlinear absorption of nanosecond 532-nm laser pulses by zinc phthalocyanine (PcZn), lead phthalocyanine (PcPb) and zinc porphyrin (PrZn) incorporated into a nanoporous-glass/polymer composite and determined the basic nonlinear absorption characteristics of these compounds in the composite host. The composite is shown to be suitable for designing nonlinear optical elements activated with organic compounds. The correlation between the characteristics of the three compounds in the composite host and liquid solvents is analysed.

Keywords: nonlinear absorption, composite, solid host, nanoporous glass/polymer, lead phthalocyanine, zinc phthalocyanine, zinc porphyrin, functional organic compound.
