X-ray Radiation in Interaction of Ultrashort and Ultraintense Laserpulse with Mo Target

  • 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.
