Haus master equation approaches have been utilized to unravel the dynamics of many different types of mode-locked lasers. Their key advantages are an intuitive understanding of the interplay of different effects such as gain and absorption as well as the fact that chromatic dispersion can be included much more easily than in the delay differential equations framework. However, to justify the validity of such Master equations for passively mode-locked lasers with an external cavity geometry that is neither in the long nor in the short cavity limit, a special set of dynamical boundary conditions is developed. The resulting system of coupled partial and ordinary differential equations allows for a uniform approach for studying instabilities either induced by dispersive effects or gain saturation in mode-locked laser irrespective of the cavity lengths.
