Abstract

The random laser dynamics above threshold limit were studied using enhanced backscattering (EBS) experiments. Laser intensity was predicted to diverge under the given conditions. Shape of backscatter cone, above the laser threshold limit, was analyzed. Generalized laser equations were used to explain the behavior of the EBS cone. The variation of pump fluence along with intensity at full width at half maximum (FWHM) condition was also reported.
