Bwj. Mcneil et al., COLLECTIVE BUNCHING OF UNCHARGED MACROSCOPIC-PARTICLES VIA AN FEL-LIKE INSTABILITY, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 407(1-3), 1998, pp. 141-145
A classical theory of the scattering of electromagnetic radiation by u
ncharged macroscopic particles is presented, in which the particles ma
y interact cooperatively via common pump and probe radiation fields. T
he collective nature of the process is manifest both in the exponentia
l growth of the bunching of the particles at the radiation wavelength
scale to form a particle grating, and in the exponential growth of the
counterpropagating probe radiation intensity. The equations describin
g this phenomenon are shown to be of the same form as those describing
the Compton FEL. (C) 1998 Elsevier Science B.V. All rights reserved.
