A simple high repetition rate molecular N2 laser is described. Experimental results for the laser operated at I atm. are given. The dependence of electrode spacing on the threshold charging voltage were measured. It was found by the experimental investigation on relations between the output power and the charging voltage with different electrode spacing (0.8-2.2mm) that a certain output power can be obtained at low operation voltage with narrow spacings. Many kinds of dyes were pumped to produce laser output at the voltage of 8kV.
