A mode of holistic effect in random laser
随机介质ZnO激光的一种整体效应模型

Based on the experimentally observed phenomena of random laser, a new physical holistic effect model is studied. The random laser is due to the interaction of the local aperiodic quasi-structure with matching pump light. The random laser in ZnO powder is simulated by numerical calculation, and the results are coincident with experimental phenomena qualitatively.
