摘要：
Angular distribution of hard x rays that are generated by focusing a femtosecond (41 fs) laser with a power density of 1.3x10(17) W/cm(2) onto a copper target was studied. The total x rays over an energy range of 4-20 keV, which were mainly assigned to bremsstrahlung, showed forward emission particularly at s-polarized incidence and the characteristic x rays (Cu K alpha emission) were almost isotropic.
