Abstract
Coherent fluctuations in the light of an argon ion laser have been investigated and laser operation free from these fluctuations has been achieved. Oscillations in the kHz range have been identified as anode oscillations and were suppressed by use of an auxiliary cathode. Oscillations related to the longitudinal magnetic field and to striations were eliminated by choice of plasma tube operating conditions. Wideband incoherent noise was less than 0.2%.Keywords
