The commissioning of the first stage (FEL-1) of FERMI@Elettra has started in the summer 2010. In this paper, we present the requirements for FEL-1 commissioning, both in terms of hardware and electron beam properties.

Frequency pulling is a well-known phenomenon leading to an output wavelength shift in a conventional laser, when the cavity and the maximum gain frequencies are detuned. We demonstrate that a similar mechanism is at play in a seeded free-electron laser (FEL). Frequency pulling thus may give the possibility of fine-tuning the FEL frequency.
