Abstract

The influence of surface roughness on the lasing performance of highly disordered ZnO films is studied. It is found that the highly disordered ZnO films with improvement in surface quality by ion-beam milling can significantly reduce the corresponding scattering loss as well as increase the slope efficiency of the light-light curves even with the presence of MgO cladding layer. Furthermore, it is noted that random lasing action is less dependent on the surface roughness of the ZnO films.
