Slippage effect on energy modulation in seeded free-electron lasers with frequency chirped seed laser pulses by Chao Feng, Haixiao Deng, Guanglei Wang, Dong Wang, Zhentang Zhao, Dao Xiang

“…It is found that the seed laser imperfection experienced by the electron beam can be significantly smoothed by the slippage effect in the modulator when the slippage length is comparable to the seed laser pulse length. This smoothing effect allows one to preserve the excellent temporal coherence of seeded FELs in the presence of large frequency chirp in the seed laser. …”
