We present the results of a comparative experimental study of optical and photorefractive
properties at room temperature of four nominally undoped, single‐crystal, commercially …

This is the first characterization of both positive and negative charge carriers as well as deep
traps in any crystal sufficient to predict photorefractive behavior for all beam geometries on …

The time development of a photorefractive grating created by intersecting 30 ps (532 nrn)
beams in a well-characterized Bi12Si020 crystal (in a static field around 1 kV/em) …

The photoinduced redistribution of charge has been characterized in Bil2GeOZO and
Bi12Si020 crystals using electron spin resonance, thermally stimulated luminescence, and …

We have measured the temperature dependence of the electron mobility in a single crystal
of photorefractive n-type cubic Bi_12SiO_20 by using a holographic time-of-flight technique …

We have developed a time-of-flight technique for measuring the mobility of photoexcited
charge carriers in certain crystals exhibiting the electro-optic effect. We used this …

We report the measurement of diffusion transport length LD, quantum efficiency φ for
photoelectron generation, and the Debye screening length and associated trap density NA …

A method to characterize the photorefractive parameters of Bi 12 GeO 20 crystal is
described. An analysis of the transient photoinduced grating under an external applied …

We present the first demonstration of a room-temperature grating fixing process in a
