Description
Two related schemes for detecting x-rays based on the scattering and the reflection of a pulsed optical probe beam by carriers produced by the absorption of a single energetic x-ray photon are described. The detection method is based on the strong carrier density dependence of the (complex) index of refraction of the exciton absorption lines in a GaAs/AlGaAs multiple-quantum-well structure. These schemes may be sued to construct a new class of very sensitive gated x-ray detectors with micron spatial resolution and temporal resolution in the 10--30 ps regime
