Strong optical asymmetry of an interference wedge with unequal-reflectivity mirrors and its use in unidirectional ring laser designs.
On the basis of theory and experiment we discuss the strong optical asymmetry in reflection exhibited by an interference wedge when it is constructed of unequal-reflectivity mirrors and show how this feature can be used to develop attractive unidirectional ring lasers. In the proposed ring cavity schemes a single interference wedge is employed simultaneously as a tuning element, as an element introducing asymmetry, and as a laser output coupler.
