Abstract

The results of experiments on the nonlinear optical confinement of a pulsed 3.8–4.2 μm laser radiation in a composite comprising a silver-halide-based dielectric matrix containing dispersed silver nanoparticles are presented. It is shown that, for a laser pulse duration of 250 ns, the energy threshold for the laser radiation confinement is 5 mJ/cm2 and the dynamic confinement range exceeds 10.

Abstract

Experimental data on the nano-and microsecond pulsed laser radiation (λ=1.315 μm) confinement in compensated GaAs are reported. There are three regions of confinement, which are controlled by radiation selfdefocusing due to single-photon absorption by deep impurity levels, self-defocusing due to two-photon absorption, and self-focusing caused by thermal dynamic lens formation.
