Free-electron lasers (FELs) deliver transversely coherent light pulses of high brightness. However, the radiation produced in FELs with self-amplified spontaneous emission (SASE) has poor temporal coherence. In seeded FELs, this is enhanced by initiating the FEL amplification process using an external, coherent light pulse. One parameter affecting the properties of the generated radiation is the chirp of the electron beam driving the seeded FEL. In this contribution, the impact of this electron beam property will be discussed.
