Experimental results are reported for C-W operation in argon and krypton as a function of magnetic fields. These experiments were performed in a tube 1.5 mm in diameter and 28 cm long. A comparison is made between the results obtained with internal mirrors and those obtained with Brewster angle windows. Experiments were carried out on mixtures of gases to determine a whether certain types of mixtures enhance the power output of given laser transitions, and b whether two laser gases could be made to operate simultaneously. It was found that in the former case the addition of mercury or neon to krypton enhanced laser operation in krypton, but that in the latter case mixtures of krypton and argon did not provide stable discharges. Spectroscopic experiments in argon and krypton lasers verified the I4 and L2 relationships at moderate powers and indicated that substantial resolution of Zeeman components occur in magnetic fields of the order of 1000 Gauss.
