Pulses of submillimeter radiation (λ∼400 μm) with a peak power of approximately 1 MW have been generated by illuminating an intense relativistic electron beam with a counterstreaming microwave pump wave (λ∼2 cm). This observation of powerful submillimeter radiation is consistent with a model of stimulated scattering which includes a resonance between the pump wave frequency and the electron cyclotron frequency as well as the occurrence of electrostatic oscillations at the beam plasma frequency.
