✦ Synopsis

In the present paper we consider an exactly soluble generalization of the Maser model which is nonlinear in the field variables. The nonlinear interaction is constructed in such a way as to preserve the well-known scaling property of the model, such that its thermodynamic limit can be defined. We conclude that in this limit the effect of the non-linear interaction is essentially to produce an intensity-dependent coupling. We conclude that the main effect of the nonlinearity is to increase the critical temperature.
