Stability of planar ring lasers with mirror misalignment

Abstract:
We consider an active cavity defined by a geometrically symmetric ring of N mirrors, each of which may have an arbitrary radius. The beam steering imposed by all possible mirror misalignment parameters is shown to diverge if the radii of curvature R(i) of the mirrors satisfy two constraints of the form K(N)({R(i)}) = 2. By comparison, the standard conditions for the stability of rays departing from the design path in a perfectly aligned ring have the form |K(N)({R(i)})|
