Abstract
An investigation is reported of nonlinear dynamics of a four-mirror Z- shaped cavity with mode locking by self-focusing. It is shown that the mode-locking region is nonuniform: it is characterised by the appeara nce of 'windows' of irregular behaviour of the system as the result of a change in the pump intensity or in the distance between the active element and a spherical mirror. Conclusions drawn from a theoretical a nalysis are confirmed by the results of a numerical experiment based o n a fluctuation model.
