Dynamics of random laser and coherent backscattering of light from ZnO amplifying random medium
We investigated the dynamics of coherent backscattering cone and random laser in a disordered gain medium of ZnO powder. Theoretical fit to the coherent backscattering cone yields a transport mean free path l approximately equal to the probe wavelength , indicating that the scattering process is in the strong scattering regime. Supernarrow emissions from the laser are accompanied by enhancement...
متن کاملCoherent Backscattering of Circularly Polarized Light from a Disperse Random Medium
To describe propagation of polarized electromagnetic wave within a disperse random medium a new Monte Carlo based technique with an adopted vector formalism has been developed. The technique has been applied for simulation of coherent backscattering of circularly polarized optical radiation from a random scattering medium. It has been found that the sign of helicity of circular polarized light ...

متن کاملCoherent backscattering of light from random media with inhomogeneous gain coefficient
We study theoretically the coherent backscattering cone of light from an amplifying random medium using realistic gain profiles which are spatially inhomogeneous. By taking into account correctly the amplification of multiply scattered waves, we are able to obtain quantitative agreements with the measured data presented in Phys. Rev. Lett. 75, 1739 ~1995! by Wiersma et al. and resolve the discr...
