Abstract Physical-and-topological model is offered on the basis of the fundamental system of equations analysis in a semiconductor diffusion-and-drift approximation and kinetic equations of lasers. It allows to carry out the numerical analysis of dynamics processes in injection lasers taking into account their structural- and- topological features, band diagrams, a dopant profile, mechanisms of a spontaneous and stimulated recombination, unevenness of spatial distributions of electrons concentration, holes and photons in active area of the laser, features of spatial distribution of current density, influence of the peripheral areas of the laser on its characteristics. The physical-and-topological model allows assuming the analysis of transition processes in lasers both at the set change in time as rating current, and voltage on contacts, depending on the boundary conditions. Based on the analysis results of numerical modeling of injection double heterostructure laser, the limits of the offered diffusive-and-drift model applicability are defined.
