Abstract The locking and unlocking phenomena of the modes of the transverse familyq=1 in a CO2 laser are investigated. The experimental results show three characteristic regions: a bistability between two helical waves of opposite handedness, a tristability among the two helicities of opposite handedness and an unlocked state, and the unlocked state. Near the locking threshold, oscillations which can be interpreted as due to the oscillations of the modal amplitudes and relative phase are also observed. These results are found to be consistent with solutions of the two-mode Maxwell-Bloch equations for class-B lasers.
