S. Werin, 2ND-ORDER BUNCHING IN AN OPTICAL KLYSTRON, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 391(2), 1997, pp. 381-384
A method to achieve spatial bunching on the double frequency of the in
duced energy spread in an optical klystron is described. Criteria nece
ssary to construct such a second order buncher and the phase space evo
lution are presented.
