Generation regimes of a solid-state coupled-cavity ring laser

Based on the experimental studies we have shown that when an inhomogeneous magnetic field is applied to an active YAG:Nd crystal, a solid-state coupled-cavity ring laser is characterised by the following generation regimes: stationary unidirectional regime, self-modulation regimes of the first and second kinds, and dynamic chaos regime. Transitions between these generation regimes were carried out when the magnet was moved over the surface of the YAG:Nd single crystal, which made it possible to control the radiation dynamics.
