Phys. Rev. Lett. 95, 043902 (2005) [4 pages]Effects of Spatial Nonuniformity on Laser DynamicsReceived 21 January 2005; published 20 July 2005 Semiclassical equations of lasing dynamics are rederived for a lasing medium in a cavity with a spatially nonuniform dielectric constant. The nonuniformity causes a radiative coupling between modes of the empty cavity, which results in a renormalization of self- and cross-saturation coefficients. Possible manifestations of these effects in random lasers are discussed. © 2005 The American Physical Society URL:
