Dynamic model of active mode locking in gas lasers

A dynamic model is proposed for describing active mode locking in gas lasers with inhomogeneous broadening. Different dynamic regimes are investigated depending on the depth of modulation of the losses. It is shown that disruption of the mode locking regime is accompanied by the appearance of more complex dynamic states, both regular and random, the shape of each individual field pulse having a complex multihump structure which is a consequence of the coherent nature of the interaction of the electromagnetic field with the active medium.
