N2 - In this experiment we observe emission of a single RF macropulse from a mode-locked FEL oscillator. The FEL employs a continuous electron beam and operates in the microwave regime. The amplitude mode-locking is achieved by modulating the attenuation of the FEL ring cavity at its round-trip frequency (∼ 27 MHz). The observed RF macropulse consists of short RF micropulses. Their period (∼ 37 ns) is determined by the modulating frequency, and their width is comparable to the slippage time (∼ 3 ns). Examples of experimental results of amplitude mode-locked FEL signals are presented for coaxial-line and waveguide cavity sections.
