Tuning Optical Nonlinearity in Epoxy plates

Abstract

In this paper we presented open and closed-aperture Z-Scan method investigating 1 and 2 mm thickness optical epoxy plate nonlinear optical responses.  The samples heated up to 175 °C and the saturable absorption (SA) and two-photon absorption (TPA) processes reviewed.  Since 2groups of the samples showed SA behavior for low intensity laser pulses then these plates promising candidate for saturable absorption devices
