Abstract

Enforcing unidirectional operation of a ring laser is an attractive way to obtain a single frequency output from a solid-state laser. Recent work suggests that a reliable way to achieve unidirectional operation is by using an intracavity traveling-wave acousto-optic (AO) modulator. The nonreciprocal behavior of this device is due to its traveling-wave nature, which causes the counterpropagating beams to suffer different diffraction losses - a consequence of the Bragg condition being satisfied at different angles of incidence for the counterpropagating beams.
