Abstract
A laboratory multi-oscillator ring laser of monoblock construction emp loying a non-planar cavity and the Zeeman effect on the helium-neon di scharge is used to bias oppositely travelling modes from lock-in. A th eoretical model of the laser is used to explain the behaviour with res pect to gain, tuning and magnetic field. Methods for stabilizing the g yro operating point and correcting for ambient magnetic fields are pre sented.
