Abstract

We experimentally demonstrate a highly stable and flawless-tuning-range multiple wavelength Brillouin fiber laser incorporating an erbium gain block. Free-running cavity modes that inherently circulate in the cavity of a Brillouin/erbium fiber laser, which limits wavelength tunability, are completely suppressed. At a Brillouin pump power of $2\mathrm{mW}$ and $130\mathrm{mW}$ of $1480\mathrm{nm}$ pump power, we obtained seven output channels. The tunability of the generated channels is only limited to $35\mathrm{nm}$ by the amplification bandwidth of the erbium gain used in the experiment. The first four channels have an output power each above $1.6\mathrm{dBm}$ with the first and the seventh channels having a peak power of $8.19\mathrm{dBm}$ and $-8.30\mathrm{dBm}$.
