“…The proposed system has the advantage that it does not use an erbium-doped fiber as a gain medium as reported earlier by other works [4][5][6][7]. The output multi- wavelength lines are obtained through careful optimization of the output coupling ratio and the employment of an optical circulator as a reflector, which is relatively more than those obtained earlier as in references [8,9].…”

“…These lasers have been developed with various mechanisms such as erbium doped fiber lasers (EDFLs) [1][2][3], amplified spontaneous emission (ASE) slicing [4] and Brillouin/Erbium fiber lasers (BEFLs) [5][6][7]. Recently, we reported a multi-wavelength laser, which uses stimulated Brillouin scattering (SBS) in a single mode fiber (SMF) as a non-linear gain medium in a ring configuration [8,9].…”

A linear cavity Brillouin fiber laser (BFL) is proposed and demonstrated for multi-wavelength operation. The BFL uses a single mode fiber (SMF) as a non-linear gain medium and an optical circulator to generate a linear cavity resonator. Two couplers are used to inject the Brillouin Pump (BP) and tap the BFL output respectively. The effect of the coupler ratio on the BFL performance is studied by keeping constant the ratio of the first coupler and varying the ratio of the second coupler. 11 simultaneous lines with a line spacing of 0.8 nm are obtained at a BP of 11.7 dBm and a coupler ratio of 95:5. The laser output is stable at room temperature with 5 lines obtained at above -30 dBm, and has the largest signal to noise ratio observed at the remaining lines. The proposed BFL has the advantage of being able to operate at any wavelength and is only dependent on the available BP wavelength. Wavelength, nmPower, dBm

“…In addition, Yb 3+ -doped fiber lasers can be used as pump sources for Raman generation [6] and they have even been considered as a suitable medium for laser tuning in novel ceramic nanocrystalline materials, although with very limited results in terms of the tuning range obtained [7,8]. Furthermore, non-linear gain in a co-doping scheme to obtain multi-wavelength lasing has recently been proposed [9]. In the first case of Yb…”

Abstract:We report wide wavelength tuning in a double-clad ytterbium-doped fiber laser. The laser cavity consists of an array of broadband high-reflection fiber Bragg gratings and a bulk grating as output coupler and wavelength selection element. The proposed fiber laser configuration combines low intra-cavity loss of fiber Bragg grating mirrors with wide wavelength tuning of bulk gratings. We demonstrate > 70 nm wavelength tuning range, limited only by the available fiber Bragg gratings.Conversion efficiency, %

A multi-wavelength laser is demonstrated using stimulated Brillouin scattering in a single-mode fiber with a feedback loop using two couplers and an optical circulator. This Brillouin fiber laser can operate at any wavelength depending on the Brillouin pump (BP) wavelength used. With a BP of 14 dBm, approximately 8 to 10 BFL lines are obtained in both forward and backward directions respectively with a line spacing of 0.16 nm. The use of the 99/1 coupler and 50/50 coupler gives the highest power and number of lines for the forward and backward outputs respectively. The maximum Stokes power obtained is approximately 8.0 dBm. The anti-Stokes lines are also obtained due to four wave mixing and bidirectional operation. The combination of forward and backward output can generate a larger number of lines with channel spacing of 0.08 nm.
