The authors 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 {approximately} 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, the authors estimate that the peak spike pulse power is {approximately} 100 MW.
