Superradiant Thomson scattering from graphite in the extreme ultraviolet
We study the Thomson scattering from highly oriented pyrolitic graphite excited by the extreme ultraviolet, coherent pulses of FERMI free electron laser (FEL). An apparent nonlinear behavior is observed and fully described in terms of the coherent nature of both exciting FEL beam and scattered radia...

| description | We study the Thomson scattering from highly oriented pyrolitic graphite
excited by the extreme ultraviolet, coherent pulses of FERMI free electron
laser (FEL). An apparent nonlinear behavior is observed and fully described in
terms of the coherent nature of both exciting FEL beam and scattered radiation,
producing an intensity dependent enhancement of the Thomson scattering cross
section. The process closely resembles the Dicke's superradiant phenomenon and
also triggers the generation of coherent, low-\textit{q} ($ |
