Abstract

Photorefractive polymers have recently shown an attractive combination of high two-beam-coupling gain coefficient (approximately equals 200cm^-1), low absorption (approximately equals 5-10 cm^-1), and fast response (few ms) at 1W/cm² writing intensity. Such materials show promise as adaptive beamsplitters for homodyne detection of transient phase shifts due to laser-based ultrasound. The performance of a photorefractive polymer composite is explored for this application.
