Abstract

Using a Singlephotoncounting CCD, Xray emission spectra of high purity Mo irradiated by ultrashort and ultraintense laser pulse was firstly detected. The experiment was carried out with the SILEX1 laser facility. The experimental results show that, for Mo target, characteristic Kshell emission (Kα) is observed in the 0.23—2.32 J energy range in addition to a broadband bremsstrahlung background, and the Xray radiation intensity, thermal radiation and bremsstrahlung increase with enhancementofthe laser power density.
