Modes of a unidirectional ring laser
Abstract
The modes of a ring-laser cavity with an extra mirror for unidirectional operation are analyzed and shown to be the same as those of a conventional ring laser. The beam from the extra mirror does not give rise to additional interferometric effects when it is reflected back into the ring cavity. Experimental results with a He-Ne unidirectional ring laser confirm this finding; operation is demonstrated in both a symmetric and an asymmetric distribution of mode amplitudes about the Doppler line center.
