| Abstract | A simple local patterning laser-assisted method to transform bulk metallic Zn into a highly efficient ZnO-based random lasing medium is reported. The method uses the plasma of CO2 laser-induced air breakdown to treat the surface of a Zn target and thus transform it into a porous, nanostructured ZnO layer, which exhibits a strong exciton photoluminescence band in the UV (380nm). We show that the synthesized ZnO-based material can work as an efficient random lasing medium, simultaneously strongly scattering and amplifying pumping light, leading to a mirrorless generation of few laser emission narrow (<0.5nm) lines within the exciton band. |
