N2 - This work demonstrates a method for achieving stable, single-frequency operation in a random fiber laser (FLRDF) by embedding an external whispering gallery mode (WGM) microresonator. While typical FLRDFs exhibit a stochastic, multi-mode output, the introduction of the microresonator as a narrow-band feedback element leads to a pure single-mode generation regime just above the lasing threshold. The resulting mode features a spectral width of less than 10 MHz, a long-term temporal stability of thousands of seconds, and an output power of approximately 3 mW, with its central wavelength determined by a resonance of the microresonator. At higher pump powers, the laser transitions to a multi-mode regime. However, a statistical analysis of the intermode intervals reveals a distinct peak corresponding to the microresonator's free spectral range (180 MHz), confirming its continued influence on the generation spectrum. These results establish the embedding of a microresonator as a robust technique for stabilizing random fiber lasers.
