An improved ring laser rotational rate sensor includes a pair of lasing cavities, each of which is comprised of a non-planar arrangement of four cavity segments. Common gain and biasing media are associated with closely-spaced segments of the two cavities. The non-planar cavity geometry supports only circularly optically polarized lasing modes thereby requiring no intracavity elements for optical biasing and eliminating the need for dithering of mirrors to control optical path length.
