Abstract
A method for attosecond pulse train generation in FEL amplifiers was recently proposed. The method uses periodic equal temporal delays between the electron bunch and co-propagating radiation to generate a modal structure in the radiation field. The modes may be phase-locked via an energy modulation in the electron beam. As a consequence of the radiation/electron delays, the relative slippage of the radiation with respect to the electron bunch is also increased and results in a longer cooperation length which improves the temporal coherence. Simulations presented here demonstrate that the longer cooperation length increases the temporal coherence. In particular, it is shown that a SASE FEL can operate in single-spike mode with longer, higher charge electron bunches than previously thought possible.
