A multiwavelength Brillouin–Raman fiber laser (BRFL) with a 51-nm wide bandwidth is proposed and demonstrated. The BRFL is configured in a half-open cavity (HOC) design with a variable optical attenuator in the cavity. The BRFL exhibits a 60 % improvement in tunability as compared to a conventional...
