Abstract

The effect of cathode temperature upon power output from a transversely excited N2 laser has been studied. An increase of 60% in output power has been observed for 75° C increase in cathode temperature. This degree of thermal enhancement did not depend significantly upon pulse repetition rate so it was possible to increase the maximum average power by the same factor of 60%. As commutation of the Blumlein was accomplished without the use of spark gaps, relatively higher pulse repetition rates were accessible. By externally heating the cathode to 100°C an average output power of 150 mW was obtained at 100 Hz for a charging voltage of 15 kV.
