Random lasing — for which disorder is exploited to enhance stimulated emission — has emerged as a paradigmatic phenomenon of complex lasers. Random lasers feature unique properties such as tunable coherence and reconfigurable spectral emission. Nevertheless, their complexity sets them apart from conventional lasers, making it challenging to determine whether random lasing is occurring. In this Expert Recommendation, I discuss experimental methods required to properly assess and demonstrate random lasing action.

确定随机激射作用

随机激射已经成为复杂激光的一种范式现象，随机激射是利用无序现象来增强受激发射的一种方法。随机激光器具有独特的特性，例如可调谐相干性和可重新配置的光谱发射。然而，它们的复杂性使它们与传统激光器区分开来，使得确定是否发生随机激射具有挑战性。在本专家建议中，我将讨论正确评估和证明随机激射作用所需的实验方法。
