This paper investigates a combined dispersion-decreasing fiber loop mirror consisting of a fourth order super-Gaussian dispersion-decreasing fiber and a Gaussian dispersion-decreasing fiber. The length ratio of the two optical fibers in the loop mirror is analyzed and optimized to achieve a high-quality ultra-short output pulse. The results show that the optimal output pulse with no pedestal and a high compression ratio of F = 49.6 can be obtain at the fiber length L = 4.3km. Compared with the traditional dispersion-decreasing fiber loop mirror, the compression ratio is increased by 18.5 times, achieving ultra-short pulse output at the picosecond level.

“…Therefore, some methods for adjusting frequency spacing of multiple Stokes lights have been reported. For example, a hybrid Brillouin-thulium MWFL with switchable spacing, corresponding to the single and double BFS at 2 µm Brillouin-thulium fiber laser cavities was reported in [12]. A novel tunable MBFL with switchable frequency spacing by using optical gain and absorption during the SBS process was reported [13].…”

“…One solution is that another gain medium is considered to incorporate into laser cavity to compensate cavity loss and improve performance of MBFL. The combination of SBS and another gain mechanism have been realized in different hybrid cavity structures such as the multi-wavelength Brillouin-erbium fiber lasers (MBEFLs) [15][16][17], multi-wavelength Brillouin-thulium fiber lasers (MBTFLs) [18][19][20], multi-wavelength Brillouin-Raman fiber lasers (MBRFLs) [12,21], and so on.…”

A multi-wavelength bidirectional Brillouin-erbium fiber ring laser with switchable Brillouin frequency spacing (BFS) is proposed and experimentally demonstrated. In the presented Brillouin-erbium ring laser, including an optical amplifier and a highly nonlinear fiber, and without any optical isolator, due to Rayleigh scattering, stimulated Brillouin scattering, and cascaded four-wave mixing initiated successively by the Brillouin pump (BP) light, the odd- and even-order Stokes lines are generated and circulate in the opposite direction in the ring cavity. The BP light and Stokes-induced Rayleigh backscattering light also simultaneously circulate in the ring cavity. Only by adjusting BP power, the gain competition between Brillouin based Stokes and cavity modes’ oscillation can be controlled, the laser output can be conveniently switched between single BFS and odd- or even-order double BFS. In addition, under the certain BP power conditions, the proposed multi-wavelength Brillouin-erbium fiber laser also can realize switchable odd- or even-order Stokes generation and Stokes generation with single BFS, with an increasing wavelength number in turn, only by simply adjusting pump power of the erbium-doped fiber amplifier. Stability and wavelength tunability of the proposed multi-wavelength bidirectional Brillouin-erbium fiber ring laser are also investigated, respectively.

“…Because the amount of the Stokes frequency shift is determined by the speed of the acoustic wave in the fiber core, and it is typically around 10 GHz for silica-based fibers. To get the more multiwavelength lasing lines, hybrid gain mechanisms are often used, such as the multi-wavelength Brillouin-Raman fiber lasers (MBRFLs) [5][6], multi-wavelength Brillouin-erbium fiber lasers (MBEFLs) [7][8][9], multi-wavelength Brillouinthulium fiber lasers (MBTFLs) [10][11][12], and so on. In addition, frequency intervals of Stokes lasing are required to be switchable in practical application, so, some methods for adjusting frequency spacing of multiple Stokes lights have also been reported [13][14][15].…”
