A simple photoionization stabilized waveguide carbon dioxide laser

“…Recently, great progress has been made in the miniaturization of pulsed carbon dioxide lasers by adopting a waveguide structure as part of the resonator (Smith et a1 1976, Nishihara et al 1976. For high-pressure operation, which is important for tuning and single mode operation, a transverse excitation scheme can be considered superior to a longitudinal excitation scheme, because a properly distributed, stable glow discharge is more easily obtained.…”
