Spatial mode dynamics in continuous-wave high-power wide-aperture quantum dot lasers is studied within the framework of Maxwell-Bloch equations. The effects of phase-amplitude coupling, junction temperature profile, carrier diffusion - capture - escape phenomena on the lateral modal dynamics is included in the model. It is shown that for low values of alpha factor and at normal operating points, there is an improvement in spatial coherence of the emitted light. It is found that active layer temperature and carrier-diffusion plays a key role in deciding the spatial mode structure in the device..
