A mean-field model for light propagation in wide-aperture, lossy semiconductor lasers is derived and validated by comparison with a full counterpropagating wave code. The model includes inhomogeneities transverse to (index or gain guiding) and along the laser structure in addition to light diffraction and carrier diffusion. The model is tested on single-stripe index- and gain-guided lasers, on multistripe index- and gain-guided laser arrays, and on broad-area lasers.
