| 摘 要： | 在SILEX-1激光器上，利用光子计数型CCD测量了超短超强激光束与高纯度Mo相互作用而产生的发射谱。实验发现， 在超短超强激光脉冲作用下， Mo等离子体辐射Kα X射线， 这一过程伴随很强的热辐射和轫致辐射。Mo等离子体Kα X射线辐射强度、 热辐射和轫致辐射随激光功率密度增加而增强。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.
