When Arthur Ashkin and his colleagues at Bell Laboratories first noticed the photorefrac tive
effect some 25 years ago, they con sidered the phenomenon a curiosity at best and a …

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 …

Sensitivity of the different known photoiefractive processes are computed from experimental
datas, and compared to an ideal non dissipative process. The minimum absorbed light …

In June 2009 about 140 researchers from all over the world will meet for three days in Bad
Honnef, Germany, to discuss newest results at the 12th topical meeting “Photorefractive …

The term “photorefractive effect” literally refers to a change in the refractive index of a
material caused by light. Recently, however, the term has been used for the subset of such …

The photorefractive effect of undoped LiNbO 3 crystals of high purity is studied by means of
two-photon excitation of picosecond light pulses. We show that two-photon photorefractive …

This is the first volume of a set of three within the Springer Series in Optical Sciences, and is
devoted to photorefractive effects, photorefractive materials, and their applications. Since the …

Exceptionally high values of photorefractive gain coefficient of up to 100 cm-1 have been
observed in Fe-doped and Fe/Tb-doped crystals of photorefractive lithium niobate. It is …

The photorefractive response time of LiNbO_3 crystal is of the order of minutes, and such a
long response time limits the crystal's practical applications. We report the photorefractive …

Since the photorefractive effect was discovered in LiNbO 3 and LiTaO 3, a great number of
reports have appeared concerning the optical absorption bands originating from intrinsic …
