Abstract
A time resolved study of the behavior of a single beam in photorefractive iron doped indium phosphide is provided down to the microsecond range, showing that infrared beam bending does occur on the microsecond time scale for moderate beam intensities. Two distinct time scales are evidenced, the behavior of which are the sign of two different photorefractive mechanisms.
► We propose a novel experimental setup for measuring dim and fast infrared processes. ► We show photorefractive effect in InP:Fe can occur in the microsecond range. ► We evidence two distinct self-bending processes occurring on different time scales.
