我们回顾了我们在主动随机介质中激光的最新工作。长期以来被认为不利于激光作用的光散射，实际上为激光提供了相干反馈。说明了具有相干反馈的随机激光器与具有非相干反馈的随机激光器的基本区别和跃迁。我们还将激光捕获在微米大小的随机介质中。捕获是由无序散射和干扰引起的。这种非传统的光约束方式在微激光器中有着重要的应用。
We review our, recent work on lasing in active random media. Light scattering, which had been regarded as detrimental to lasing action for a long time, actually provided coherent feedback for lasing. The fundamental difference and transition between a random laser with coherent feedback and a random laser with incoherent were illustrated. We also trapped laser light in micrometer-sized random media. The trapping was caused by disorder-induced scattering And interference. This nontraditional way of light confinement has important applications to microlasers.
