A new pump-seeded, short-cavity Brillouin ring laser source layout intended for Brillouin sensing applications is showcased, showing increased high maximum output (1.5 mW), a strong linewidth narrowing effect (producing light with a linewidth of 10 kHz) and limited RIN (~-145 dB/Hz), providing an ultranarrow, highly stable BRL source that can also be employed as a pump-probe source for BOTDA applications.
