A sequence of 50‐ to 75‐nsec high‐voltage pulses in combination with photoionization produce spatially uniform continuous electron densities of 2 × 1011with a 10–20% ripple at 20 000 Hz in 150‐Torr CO2laser mixes. A separate continuous electric field ranging from 3 to 6 kV/cm atm is used to heat the electrons, which loads greater than 0.25 J/cm3atm into the plasma without arc breakdown. As is the case with electron beam plasmas,E/Pandnemay be controlled independently. Hence, electron beams, flow constrictions, etc., are not necessary to produce uniform plasmas for cw high‐power electric gas laser systems.
