R. Tatchyn, PARTICLE-BEAM MODULATION TECHNIQUES FOR THE GENERATION OF SUBFEMTOSECOND PHOTON PULSES IN THE VUV SOFT X-RAY RANGE/, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 358(1-3), 1995, pp. 56-59
In this paper we consider the energy modulation of a short subinterval
of an electron bunch at the scale length of visible/UV laser light. P
ossibilities for converting this modulation into a high-gain FEL-type
density fluctuation to produce a coherently-enhanced subfemtosecond ra
diation pulse in the VUV/soft X-ray range are discussed.
