Ultrafast high-intensity X-rays can be generated from the interaction of high intensity femtosecond laser via Compton backscattering Hartemann et al. 2005 relativistic nonlinear Thomson scattering Ueshima et al. 1999 Kaplan Shkolnikov 2002 Banerjee et al. 2002 and laser-produced betatron radiation Phuoc et al. 2007 . In synchrotron facilities electron bunch slicing method has been adopted for experiments Schoenlein 2000 Beaud et al. 2007 . Moreover X-ray free electron lasers Normile 2006 were proposed and have been under construction. The pulse duration of these radiation sources are in the order of a few tens to hundred fs. There are growing demands for new shorter pulses than 10 fs. The generation of intense attosecond or femtosecond keV lights via Thomson scattering Lee et al. 2008 Kim et al. 2009 is attractive because the radiation is intense and quasi-monochromatic. This radiation may be also utilized in medical Girolami et al. 1996 and nuclear physics Weller Ahmed 2003 area of science and technology. When a low-intensity laser pulse is irradiated on an electron the electron undergoes a harmonic oscillatory motion and generates a dipole radiation with the same frequency as the incident laser pulse which is called Thomson scattering. As the laser intensity increases the oscillatory motion of the electron becomes relativistically nonlinear which leads to the generation of harmonic radiations. This is referred to as relativistic nonlinear Thomson scattered RNTS radiation. The RNTS radiation has been investigated in analytical ways Esarey et al. 1993a Chung et al. 2009 Vachaspati 1962 Brown et al. 1964 Esarey Sprangle 1992 Chen et al. 1998 Ueshima et al. 1999 Chen et al. 2000 Kaplan Shkolnikov 2002 .
