Abstract

A new type of random laser structure composed of ZnO particles and Au which embedded in waveguide is proposed. The distribution of the optical filed and the modes spectra in the random laser system are numerically simulated by using the finite difference time domain (FDTD) method. We also compare and analyze the optical field and the modes spectra of random laser by using Au particles and Au film

respectively. The results show that when Au particles were embedded in waveguide

the number of modes reduced and the monochromaticity was better than Au film which only had a better laser output intensity.
