Random lasing with spatially nonuniform gain
Review articleOpen access
Abstract:

Highlights•Spatial and spectral properties of random lasing with spatially nonuniform gain were investigated.•The pumping light was described individually and coupled into the rate equations by using the polarization equation.•The spatially nonuniform gain comes from the multiple scattering of this pumping light.•In strong scattering regime, new lasing modes appear with nonuniform gain as the localization area changes.
