A. Gerwens et al., ACTIVATION OF CERIUM-DOPED STRONTIUM-BARIUM NIOBATE FOR INFRARED HOLOGRAPHIC RECORDING, Optics communications, 135(4-6), 1997, pp. 347-351
Homogeneous illumination of Sr1-xBaxNb2O6:Ce (0.25 less than or equal
to x less than or equal to 0.75; SBN) crystals with a green light puls
e allows subsequent recording of a holographic grating with infrared l
ight pulses. The grating can be read nondestructively with infrared li
ght and can be erased by illumination with green light. The results in
dicate that the charge transport in Sr1-xBaxNb2O6:Ce must be described
by a two-level model.
