Abstract:Two far i.r. lines from a pulsed helium laser have been accurately measured with a metal grid Fabry-Perot interferometer at wavelengths of 95.763 ± 0.006 μm and 216.12 ± 0.01μm. The laser output critically depends on the plasma conditions in the laser during the excitation phase. The rapid increase in collision frequency at this time limits the duration of the laser emission.
