The application of even modest magnetic fields to the amplifying material in the helium-neon laser profoundly modifies the operational characteristics of the laser. The magnetic field introduces a Faraday effect and a Zeeman effect. Both of these effects tend to reduce the power output of the laser. A simple theory is set forth which describes the impact of these effects on the output. The experimental work which was carried out with a laser oscillating at a wavelength of 6328 A is generally in agreement with the theory. An attempt is made to explain some observed deviations from the expected results. Author
