We investigate the angular distribution of luminescence dissymmetry of random lasing in the mixture of rhodamine 6G and titanium dioxide nanoparticles upon a biocompatible natural material substrate. We characterize the light via measuring the angular distribution of its luminescence dissymmetry factor, which reaches an unusually high maximal value at some specific angle depending on the handedness of its polarization. This random laser source can be used in numerous potential optoelectronic applications which require light emission of distributed luminescence dissymmetry or of high luminescence dissymmetry.
