The effect of helium, neon, argon, and hydrogen additions on the average radiation power level and the
maximum pulse repetition rate in a low-pressure nitrogen laser pumped by a longitudinal discharge is studied.
It was found that the introduction of helium, neon, argon, and hydrogen into the active element of a nitrogen
laser with a partial pressure of 5 Torr at an optimal nitrogen pressure of 18 Torr promote an increase
in the average radiation power level by 20 – 30 % and does not affect the maximum pulse repetition
rate. The addition of neon or argon to pure nitrogen does not lead to noticeable changes in the average radiation
power and the maximum pulse repetition rate. In an active element made of beryllium ceramics
300 mm long and 4 mm in diameter, the maximum values of the average radiation power of up to 115 mW
were achieved in pure nitrogen (РN2 = 18 Torr), 120 mW when using nitrogen with the addition of hydrogen
in the ratio РN2 : РH2 = 18 : 5 Torr and 140 mW when using nitrogen with the addition of helium in the ratio
РN2 : РHe = 18 : 5 Torr at the maximum pulse repetition rates of 500 – 600 Hz.
Key words: low pressure nitrogen laser; average radiation power; radiation energy in a pulse; the duration
of the radiation pulse; longitudinal discharge; metastable states; pulse repetition rate
