“…In the measurement, the C-band EDFA, which operates at the wavelengths of 1528-1562 nm, has the characteristics of 13 dBm saturated output power and <5.5 noise figure (NF). Besides, the polarizer and PC inside ring cavity are utilized to ensure the fiber laser operating in singlepolarization state, this can introduce polarization dependent loss (PDL) for decreasing the number of longitudinal-modes and suppressing mode-hopping [13]. Here, a 2 × 2 CP is employed to produce a sub-ring in the 'block a', as illustrated in figure 1.…”

In this demonstration, we propose and investigate a stable C-band erbium-doped fiber (EDF) laser with compound-ring cavity. To achieve wavelength tunability with single-longitudinalmode (SML) output, the sub-ring scheme and fiber Bragg grating (FBG) are used inside the ring cavity. Here, different lasing wavelengths can be selected by employing different Bragg wavelengths of FBGs. In this experiment, the obtained optical signal to noise ratios (OSNRs) and output powers are larger than 44.5 dB and 8.0 dBm respectively in the tuning range of 1531.70-1547.88 nm. Moreover, the output wavelength and power fluctuations of the proposed EDF laser are less than 0.02 nm and 0.1 dB in an observation time of 30 min, respectively.

“…Multi-wavelength switchable erbium-doped fiber lasers (EDFLs) have many advantages such as flexible wavelength tunability, long service life, narrow linewidth, and high signal-to-noise ratio (SNR) [1][2][3]. Thus, they are utilized in the fields of light detection and ranging, fiber sensing, fiber communications, biomedicine, spectroscopy, etc [4][5][6]. In the past few years, several techniques have been proposed to realize switchable multi-wavelength EDFL emission.…”

A multi-wavelength switchable C-band erbium-doped fiber laser based on a hybrid comb filter composed of a Sagnac loop and Mach–Zehnder interferometer (MZI) is designed and experimentally demonstrated. In the designed ring cavity fiber laser, the MZI is composed of bi-tapered single-mode fiber fabricated by etching with hydrofluoric acid. In the experiment, the wavelength intervals in the comb spectra of the Sagnac loop and MZI are 3.4 and 18.8 nm, respectively, and by combining the Sagnac loop and MZI, measurements of the hybrid comb spectrum are obtained. When the pump power is 91 mW, lasing occurs at 1529.2 nm. Adjustment of the variable attenuator (VA) can provide 1541.9 and 1558.6 nm single-wavelength switchable lasers, for which the maximum peak power difference is less than 3.59 dB, the signal-to-noise ratio (SNR) exceeds 19.25 dB, and the peak power fluctuation is less than 0.34 dB over a 30 min scan time at 26 °C. For dual-wavelength switchable laser emission, four different sets of wavelengths can be realized, and the SNR exceeds 15.57 dB with power fluctuations of less than 1.6 dB, under the same monitoring conditions. By further adjusting the VA, stable and tunable triple-wavelength lasing is also realizable; under these conditions, the SNR exceeds 15.02 dB and the power fluctuation is less than 0.91 dB. Furthermore, four- and five-wavelength lasing can also be achieved by adjusting the VA again, with SNRs exceeding 19.05 and 14.98 dB, respectively.

“…A polarization-maintaining fiber Bragg grating and a Fabry-Perot (F-P) fiber filter were used in the design of a traditional fiber laser to facilitate a dual-wavelength output with power separately at −2.259 dBm and 0.568 dBm, a 3 dB bandwidth separately at 0.102 nm and 0.1402 nm, and a central wavelength separately at 1547.778 nm and 1548.222 nm [7]. A dual-wavelength fiber laser was developed based on stimulated Brillouin scattering, which facilitated discretely tunable beat-frequency generation up to 27.5 GHz, with linewidths of <3 Hz [8][9][10]. To the best of our knowledge, a narrow linewidth dual-wavelength all-solid-state laser for simultaneous quasi-three-level and four-level lasing based on intra-cavity pumping has not been reported.…”

A narrow linewidth, no-gain competition, 912 nm quasi-three level and 1064 nm four-level dual-wavelength laser is presented for the first time. This system consists of an intra-cavity pumped Nd:YVO 4 laser emitting at 1064 nm, using a 912 nm Nd:GdVO 4 laser. A Fabry-Perot etalon is used to compress the linewidth located at the common parts of the 912 nm and 1064 nm laser resonators. When the etalon, with an angle of refraction of 15°, was introduced into the cavity, the narrow linewidth dual-wavelength laser was obtained. The corresponding minimum linewidths were 0.284 nm and 0.627 nm.
