“…The power fluctuation of the output was approximately 5 dB with an side mode suppression ratio (SMSR) up to 22 dB and SNR of 10.7 dB. A similar approach can also be seen in the use of a nonlinear amplifying loop mirror [15,16], which was implemented in Tao et al [17] in an erbium-doped all-fiber dual-wavelength mode-lock setup. The proposed laser generated an output with a vast range of tunability of 52 nm around the C-and L-bands.…”

In this work, we successfully demonstrated an all-fiber, dual-wavelength holmium-doped fiber laser (HDFL) with a tunable wavelength spacing range of 8 nm to 24 nm. The HDFL utilizes a Lyot filter to obtain a stable dual wavelength output, with the Lyot filter being constructed from a polarizer, a 20 m polarizing maintaining fiber (PMF) and two polarization controllers (PCs). The dual-wavelength HDFL has an operating wavelength range from 2072.1 nm to 2097.2 nm and a maximum spacing of 24 nm between the lasing wavelengths as well as a signal-to-noise ratio of up to 45 dB and a side mode suppression ratio as low as 0.15 dB. The HDFL is highly stable, with the lasing output have a low power fluctuation of only 2.3 dB over a continuous operation period of 75 min. The proposed HDFL would have substantial applications as a low cost laser source for sensing applications beyond the 2 µm region, particularly those that require a control signal.

“…A common method involves using a tunable bandpass filter for selecting the mode-locking wavelength. Devices like fiber Bragg Grating (FBG), long-period fiber grating (LPFG), and Sagnac loops have been extensively studied [5][6][7]. Moreover, research has focused on intracavity loss control using tunable-ratio optical couplers (TROC) or variable optical attenuators (VOA) [8,9].…”

We achieved the first demonstration of a wavelength-tunable mode-locked fiber laser in the L-band using allpolarization-maintaining (all-PM) nonlinear polarization rotation (NPR). The all-PM configured laser features excellent repeatability and reliability. By increasing the pump power from 82.5 mW to 135 mW, a center wavelength-tuning from 1576.2 nm to 1592.2 nm is obtained. This non-mechanical tuning mechanism opens new possibilities for L-band wavelength-tunable lasers and their applications.
