Abstract

Random lasing properties were investigated with and without hexagonal boron nitride using rhodamine 6G doped film as the gain medium. Aluminum nitride nanocolumns as scatterers were introduced on top of the hBN layer. A lower threshold of 1.38 mJ/cm2 was achieved in samples containing hBN. Significantly higher threshold was observed when no hBN was present. Results suggest the potential of utilising hBN as an ultrathin flexible substrate for random lasing applications.
