Abstract
In this article, low-threshold random laser with one mirror and feedback is investigated in PMMA film containing Rhodamine 590 and TiO2 nano-particles. Incoherent and coherent laser emission is observed. Optics microscopy and Scanning Probe Microscopy are used to investigate the film structure and the principle of incoherent and coherent laser is analyzed.
