Stimulated Brillouin scattering (SBS) in a microcavity is usually realized by employing a wavelength tunable external cavity diode laser (TECDL) as the pump source. In this Letter, we report the observation of SBS in a high Q microcavity based on a TECDL-free scheme. The microcavity is employed as a mode-reflecting mirror for constructing a fiber-ring laser and, simultaneously, pumped by the fiber-ring lasing with intrinsic resonance latching. Several regimes are observed in a microcavity with a diameter of ∼215 μm, such as single lasing pumped SBS and multiple regular lasing pumped SBSs (single or cascaded). The microwave signals from the beat notes of the composite output lasing are measured with full-width at half-maximum on the scale of kilohertz at ∼11 and ∼22 GHz, indicating the high coherence between the pump and the Brillouin lasing.
微腔中的受激布里渊散射（SBS）通常通过使用波长可调谐外腔二极管激光器（TECDL）作为泵浦源来实现。在本信函中，我们报告了基于无TECDL方案在高Q微腔中对SBS的观测。该微腔用作模式反射镜以构建光纤环形激光器，同时由具有固有共振锁定的光纤环形激光进行泵浦。在直径约为215μm的微腔中观测到了几种情况，例如单激射泵浦的SBS和多个规则激射泵浦的SBS（单个或级联）。复合输出激射的拍频产生的微波信号在约11和约22GHz频率下，在千赫兹尺度上的半高全宽被测量，这表明泵浦与布里渊激射之间具有高相干性。
