Abstract
The well known self-transparency effect, originated from the nonlinear optical behavior of a scattering sample, has been observed for a solid polymeric blend (PMMA-EVA) at a low intensity threshold (25 W cm-2), using a Ar+ laser cw radiation. An interpretation of the experimental results in terms of a nonlinearity of thermal origin is given, using the theory of nonlinear scattering in heteroheneous media. Use of this polymeric blend as a nonlinear material is suggested. © 1994.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
