### Abstract

This study starts off from the mean field Maxwell-Bloch equations, written in the complex Lorenz form. When the transverse domain is assumed to be of infinite extent and for positive detunings, atomic resonance > 0, these equations have exact transverse travelling wave solutions that correspond to an off-axis emission from the laser. The laser selects a pure travelling wave that 'tilts' the laser emission so as to fit the cavity and allow it to operate on resonance. This assertion is borne out by nonlinear analysis close to threshold and by numerical simulations of the equations. In particular, a combination of two opposing waves, a standing wave, is unstable, collapsing to a single travelling wave. We performed numerical simulations of the Lorenz equations with these boundary conditions with both one and two transverse dimensions.
