These are due to a nonlinear modulation of the optical micropulse shape and phase by the electrons, which leads to the formation of a train of subpulses. Experimentally, the oscillations have been found to depend on the slippage distance and on the desynchronism between optical pulses and electron bunches, comparing well with theoretical predictions.}, year = {1993}, journal = {Physical Review Letters}, volume = {70}, number = {22}, pages = {3412-3415}, month = {May 31}, isbn = {0031-9007}, doi = {10.1103/PhysRevLett.70.3412}, language = {eng}, }
