Abstract
We present the comparative study on three representative methods for producing the coherent multi-color radiation in a seeded free electron laser based on the high gain harmonic generation (HGHG). In these schemes, either the electron beam density or the seed laser intensity is modulated to produce a coherent radiation pulse train that yields multiple spectral lines in FEL output. Realistic beam parameters obtained in 3D start-to-end simulations are used to compare the performance of each scheme.
