Nicolas Fressengeas @fresseng activity timestamp 9 years ago Fast photorefractive self-focusing in InP:Fe at infra-red wavelengths: simulations and experimental results Photorefractive self focusing in InP :Fe semiconductor is analysed experimentally and theoretically at 1.06 and 1.55 µm. We show how the self focusing can be controlled by tuning various parameters. Short response times (10µs) are measured for low intensities (10W/cm²) Reply Boost Like More actions Copy link Flag this media Block
