The transition from the transmission to the reflection regime for an Ar+-laser beam propagating in the new polymeric blend PMMA-EVA at a nonlinear interface has been observed. A comparison between the experimental data and a calculation of the input optical intensity at which this transition should occur (1.45 x 10(7) W m-2) is presented using Kaplan's theory. The results suggest the presence of thermally induced optical bistability in PMMA-EVA.

Abstract
The transition from the transmission to the reflection regime for an Ar+-laser beam propagating in the new polymeric blend PMMA-EVA at a nonlinear interface has been observed. A comparison between the experimental data and a calculation of the input optical intensity at which this transition should occur (1.45 x 10(7) W m-2) is presented using Kaplan's theory. The results suggest the presence of thermally induced optical bistability in PMMA-EVA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
