Abstract

Molecular gas lasers pumped by electron-beam-sustained-discharge CO₂ lasers may make possible high peak power (<1 MW), long-pulse (<1 gs) submillimeter-wave sources. Such a source technology may be an attractive option to rapidly pulsed free electron lasers for small angle (<10°) collective Thomson scattering diagnostics in fusion burning tokamaks. As an example, it may be possible to build a 16 MW, 10 μs, 152 μm ammonia laser for a 7° ITER tokamak diagnostic of ion temperature and alpha-particles with a signal to noise ratio of 30 per pulse.
