Abstract: Within the frames of the nonlinear resonant model the analysis of radiation processes stability in semiconductor laser quantumwell structures has been conducted. At the account of light field spectrum linewidth broadening and near dipole interaction factor in condition of unhomogenious broadening of gain resonance the possibility of the arising of output self-oscillatory mode is theoretically predicted.

Keywords: resonance interaction, light field spectrum linewidth broadening, self-sustained pulses of light intensity.
