An attosecond x ray pulse with known spectrotemporal information is an essential tool for the investigation of ultrafast electron dynamics in quantum systems. ultrafast free electron lasers (fels) have the unique advantage on unprecedented high intensity at x ray wavelengths. however, no suitable method has been established so far for the spectrotemporal characterization of these ultrashort x.

Self referenced spectral interferometry with extended time excursion (srsi ete) is a powerful method for single shot characterization of the temporal contrast of a high peak power laser, which has high temporal resolution but a low dynamic range. here, a temporal contrast reduction method is proposed that uses the cascaded kerr lens process in two thin glass plates. combined with the srsi ete.
