摘要：

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.
