摘要
A dual-beam platform is developed for all-optical Thomson/Compton scattering,with versatile parameter tuning capabilities including electron energy,radiation energy,radiation polarization,etc.By integrating this platform with a 200 TW Ti:sapphire laser system,we demonstrate the generation of inverse Compton scattering X-/gamma-rays with tunable energies ranging from tens of keV to MeV.The polarization of X-/gamma-rays is manipulated by adjusting the polarization of the scattering laser.In the near future,by combining this platform with multi-PW laser facilities,our goal is to explore the transition from nonlinear Thomson scattering to nonlinear Compton scattering,ultimately verifying theories related to strong-field quantum electrodynamics effects induced by extreme scattering.
