Photorefractive effect at 633 nm in semi‐insulating cadmium sulfide
P Tayebati, J Kumar, S Scott - Applied physics letters, 1991 - pubs.aip.org
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.
The response time scales sublinearly with intensity and is independent of grating spacing. At
a maximum intensity of 80 mW/cm2, a response time of 0.9 ms is obtained. The
photorefractive sensitivity is the largest among photorefractive material operating in the
visible range.
