Random Laser in Weakly Scattering Structures
A random laser in weakly scattering structure formed by spatial speckle is investigated. Both phenomena induced by coherent feedback and intensity feedback are observed in the same system. The result shows that two kinds of feedback are related, but independent of each other. A physical mechanism of cavities coupling is proposed based on experimental investigations. The mode characteristics of weakly scattering random laser can be well explained through this mechanism.
