A relationship between the axial magnetic field necessary to extinguish oscillation from a Brewster-angled laser and spontaneous intensity is derived. The results are used to measure the Doppler width of the spontaneous light at 6328 Å and, after an adiabatic collision process is allowed for, to find the gas temperature Using the same measurements, the gain of the system is evaluated as a function of input power, as is the ratio of the population of the upper and lower laser levels.
