Recent experimental studies have revealed for the first time some basic features of pulsed. relativistic (300-600 keY) backward-wave oscillators such as starting current, axial mode locking, and multifrequency
operation. Above a critical beam current a gradual degradation of the spectral purity of the electromagnetic radiation is observed, culminating in the onset of stochastic oscillations.
