Bi-functional nonlinearities in monodisperse ZnO nano-grains - Self-consistent transport and random lasing

arXiv:1209.4552 · doi:10.1063/1.4893526

Abstract

We report a quantum field theoretical description of light transport and random lasing. The Bethe-Salpeter equation is solved including maximally crossed diagrams and non-elastic scattering. This is the first theoretical framework that combines so called off-shell scattering and lasing in random media. We present results for the self-consistent scattering mean free path that varies over the width of the sample. Further we discuss the density dependent correlation length of self-consistent transport in disordered media composed of semi-conductor Mie scatterers.
