The relativistic electron beams produced by pulse-line accelerators (induction Linacs1, IRED accelerators2, and radial line accelerators3) can have suffiicent intensity to shift the laser interaction to the regime where collective electron oscillations participate in the wave amplification process. Free electron lasers with collective interactions can have sufficient gain so that practical amplifiers can be developed in addition to oscillators. Also there is potential for high efficiency in converting electron kinetic energy to photon energy. The electron energy characteristic of pulse-line accelerators (roughly 1–10 MeV) is relatively modest and lasers employing these acclerators are expected to operate in the wavelength range extending from millimeters to the near infrared. Electron beam pulse duration 10 ns – 10 μs is much longer than with r.f. accelerators, so that linewidth of the radiation may be compatible with good coherence even with operation in the millimeter wave regime.
