英文摘要 | diagnostic measurement of single picosecond event in high energy density physics, laser fusion, plasma radiation, and combustion, is of great importance. however, the measuring of the shape of the single x-ray pulse and the synchronization of x-ray and the laser pulse in picosecond resolution is still a great challenge. restricted by the transit time of electrons, the time-resolution limit of a conventional framing camera based on the microchannel plate is 40 ps. centered on the full-optical modulation effect of the light-probe, a novel method for x-ray detection of picoseconds temporal resolution based on low temperature gaas is proposed in this work. the basic physical mechanism of the detector can be explained in both macroscopical and microcosmic ways. in the macroscopical way, the x-ray radiation absorption in the sensor material produces a transient, non-equilibrium electron-hole pair distribution that results in a transient differential change of the local refractive index, which is then sensed by the reflectivity changes of the optical probe beam. in the microcosmic way, x-ray absorption creates photoelectrons and the core level holes are subsequently filled through auger or fluorescence processes. these excitations ultimately increase conduction and valence band carriers that perturb optical reflectivity. |
