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