Nonlinear refraction and nonlinear absorption in nanoporous glass composite activated by functional dyes

Abstract

The nonlinear refraction and nonlinear absorption of 40 nanosecond (FWHM) 532 nm pulses through the samples made of nanoporous glass polymer composite doped with phthalocyanine and porphyrin dyes is investigated. The laser damage resistance of 28 nanosecond (FWHM) 532 nm pulses in nanoporous glass polymer composite is measured. It is demonstrated that the nanoporous glass polymer composite is a good solid-state host material for nonlinear element of laser optics.
