Abstract

A low-threshold random laser with one mirror and feedback is investigated in the PMMA film containing rhodamine 590 and TiO2nano-particles. Incoherent and coherent laser emission is observed. Effect of particle concentration on light emission is explored, and the optimum particle concentration is obtained. Optical microscopy and scanning probe microscopy are used to investigate the film structure, and the principle of incoherent and coherent laser is analysed.
