We report the first observation of the photorefractive effect in cadmium sulfide at low optical
power. The maximum gain coefficient measured with no applied field at 633 nm is 0.3 cm− 1 …

I wish to extend my thanks to Glass et al.[1] for calling my attention to some of the earlier
works on photorefractive sensitivity. After reading these earlier papers, I found that, although …

The ac field technique leading to the enhancement of the photorefractive effect is applied to
vanadium-doped cadmium telluride. Net photorefractive gain is obtained for the three …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

The papers collected in this Feature are representative of the theoretical and experimental
results presented at the Second Topical Meeting on Photorefractive Materials, Effects, and …

We report our observation of the photorefractive effect in undoped aluminum nitride. We
measured the coupling constant and the formation rate as a function of pump intensity at a …

Abstract In a recent Letter,[1] Yeh presents a derivation of the response time of a
photorefractive material and asserts that this response time is a fundamental limiting value …

Semiconductors as photorefractive materials sensitive to infrared light are among others
advantageous since they have small response times. Typically these time constants are in …

Photorefractive materials have been used in a wide variety of applications, as will be
discussed later. These materials have several features which make them particularly …
