The realization of ZnO random cavities may be an appropriate approach to fabricate low-cost ZnO laser diodes as there is no stringent requirement in the design of the disordered media provided that they can sustain enough optical gain and feedback within the media to achieve closed-loop random lasing. However, ZnO random lasers suffer from some drawbacks such as relatively higher threshold than conventional lasers, lack of directionality and coherency light emission as well as the difficulty to realize electrically pumped ZnO random lasers. In this paper, a short review on the possibilities to realize low threshold directional electrically pumped ZnO random laser diodes.
