Photorefractive Properties of Ce- and Ca-Doped Sr(0.6)Ba(0.4)Nb2O6

摘要

We present the results of experimental study of the absorption coefficient, two beam photorefractive coupling constant, and photorefractive response time of a doubly Ce- and Ca-doped Sr0.6Ba0.4Nb206. This crystal displays enhanced photorefractive response at near infrared wavelengths when compared to Ce-doped SBN:60. The temperature dependence of the coupling constant over the range from -30 to 40 C has also been studied. Photorefractive properties, Reprints, Cerium, Calcium, Strontium barium niobates. (mjm)
