The time development of a photorefractive grating created by intersecting 30 ps (532 nm) beams in a well-characterized Bi12SiO 20 crystal (in a static field around 1 kV/cm) unambiguously reveals the mobility of photoexcited electrons to be 0.24±0.07 cm2/V s through what is essentially a "time-of-flight" measurement.
