Nanosecond and Subnanosecond Investigations of Intrinsic Optical Limiting Mechanisms in Photorefractive and Semiconducting Materials
Abstract
This program has been directed at exploring the fundamental physics underlying optical nonlinearities in a variety of materials, including semiconductors, organometallics, and photorefractive ferroelectrics, that have potential applications to eye and sensor protection. In addition, simple 'proof- of-principle' optical limiting devices have been demonstrated and analyzed. Specific materials have included GaAs and Si at 1.06 micrometers, and at 532 nm the semiconductor GaP, the organometallic compound known as King's complex, and the ferroelectric oxide BaTiO3. This document summarizes progress on the program, delineate; conclusions drawn from the research, provides recommendations for future research, and briefly describes research that will continue (until September 1995) on this contract under AASERT funding.
