Abstract.
We study generation of x-rays and gamma rays through Thomson backscattering of a
probe laser pulse off attosecond relativistic electron bunch generated by accelerating
laser pulse from a thin plasma layer. With the help of two dimensional numeric
simulation, typical parameters of electron bunches are derived. In particular,
the energy of the electrons in the bunch can reach hundreds of MeV, and the
charge of the bunch range from tens of picocoulomb to several nanocoulomb. It
is shown that in this scheme, using modern lasers, it is possible to generate
attosecond x-ray and gamma beams with maximum energy of several MeV.
Key words:
super-intense laser pulses, relativistic attosecond electron beams, attosecond
x-ray beams.
