Abstract
A wavelength-interval switchable Brillouin-Raman random fiber laser(BRRFL)based on Brillouin pump(BP)ma-nipulation is proposed in this paper.The proposed wavelength-interval switchable BRRFL has a full-open cavity configu-ration,featuring multi wavelength output with wavelength interval of double Brillouin frequency shifts.Through simulta-neously injecting the BP light and its first-order stimulated Brillouin-scattered light into the cavity,the laser output exhibits a wavelength interval of single Brillouin frequency shift.The wavelength-interval switching effect can be manipulated by controlling the power of the first-order stimulated Brillouin scattering light.The experimental results show the multiwave-length output can be switched between double Brillouin frequency shift multiwavelength emission with a broad bandwidth of approximately 60 nm and single Brillouin frequency shift multiwavelength emission of 44 nm.The flexible optically controlled random fiber laser with switchable wavelength interval makes it useful for a wide range of applications and holds significant potential in the field of wavelength-division multiplexing optical communication.
