Nicolas Fressengeas @fresseng activity timestamp 9 years ago Fast photorefractive self-focusing in InP:Fe semiconductor at infrared wavelengths Photorefractive beam self-trapping is investigated in InP:Fe and is shown to occur within tens of microseconds after beam switch on. This fast response time is predicted by an analytical theoretical interpretation based on a simple photorefraction model which suggests buildups in a time range consistent with experiments.
