我们研究了二维限制对在非相干反馈（扩散）状态下运行的经典随机激光系统的激光特性的影响。将 250 nm 金红石 (TiO2) 颗粒在罗丹明 6G 溶液中的悬浮液插入光子晶体光纤的中空芯中，产生第一个随机光纤激光器和新颖的准一维随机激光几何结构。与批量格式的类似系统进行比较表明，随机光纤激光器的效率至少高出 2 个数量级。
We investigate the effects of two-dimensional confinement on the lasing properties of a classical random laser system operating in the incoherent feedback (diffusive) regime. A suspension of 250 nm rutile (TiO2) particles in a rhodamine 6G solution was inserted into the hollow core of a photonic crystal fiber generating the first random fiber laser and a novel quasi-one-dimensional random laser geometry. A comparison with similar systems in bulk format shows that the random fiber laser presents an efficiency that is at least 2 orders of magnitude higher.
