Ga. Bogatova et al., OPTICAL RESONATORS FOR A HIGH-POWER FEL, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 359(1-2), 1995, pp. 61-62
Schemes of an optical resonator for a high power FEL are considered. S
everal configurations of two-mirror optical resonators utilizing asphe
rical mirrors are suggested. The advantages of such resonators for a h
igh power FEL are discussed.
