摘要：

We report the observation of “spikes” of high-intensity radiation emitted from a 2-mm wavelength Raman free electron laser (FEL) oscillator. The spikes are correlated with a well-developed sideband spectrum, including several sideband harmonics, together with the carrier. A pulse width ~ 150 ps is obtained from analysis of data obtained with a two-slit “Young's experiment.” An even shorter pulsewidth results from a numerical model. Using an elementary model of the spike, we estimate that the peak spike pulse power is-100 MW. © 1990 IEEE
