G. Dattoli et al., A MODEL FOR THE SATURATION OF A STORAGE-RING FREE-ELECTRON LASER, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 365(2-3), 1995, pp. 559-563
The dynamical properties of a storage ring free electron laser oscilla
tor are reproduced using a model combining three different saturation
mechanisms: laser induced energy spread of the e-beam, associated bunc
h lengthening and longitudinal synchronism between laser and electron
pulses. The stationary output power is shown to be always linked to th
e power emitted via synchrotron radiation in one machine turn by the c
irculating e-beam.
