| 英文摘要 | the characteristics of k alpha x-ray sources generated by p-polarized femtosecond laser-solid interactions are experimentally studied in the relativistic regime. by use of knife-edge image technique and a single-photon-counting x-ray ccd camera, we obtaine the source size, the spectrum and the conversion efficiency of the ka x-ray sources. the experimental results show that the conversion efficiency of ka photons reaches an optimum value of 7.08 x 10(-6)/sr at the laser intensity of 1.6 x 10(18) w/cm(2), which is different from the reich's simulation results (reich et al., 2000 phys. rev. lett. 84 4846). we find that about 10% of laser energy is converted into the forward hot electrons at the laser intensity of 1.6 x 10(18) w/cm(2). |
