Paper Abstract

The ultrafast all-optical solid-state framing camera(UASFC) based on semiconductor photorefractive effect is a new type of X-ray ultrafast imaging system. The temporal resolution of UASFC is determined by the response time of the semiconductor. We improve the pump-probe experiment to measure the time response of GaAs/AlGaAs. In our recent experiments, the full width of half maximum (FWHM) is about 2ps, and the dynamic test result of the UASFC system, which use these AlGaAs samples, is 2.5ps. The results verify feasibility of the measurement and provide necessary methods for the further construction of high performance UASFC system.
