“…By means of optimized length of unpumped EDF, the beat frequencies corresponding to the multimode lasing disappeared when a saturable absorber is introduced [36] so, lasers that can be wavelength-swept over the entire C-band (1520nm-1570nm) window with linewidth less than 0.7 kHz [37], laser that can also achieve switching modes among several wavelengths by simple adjustment of two polarization controllers in the cavities [38], C-plus L-band fiber ring laser with wide wavelength tunability and single-longitudinal-mode oscillation [39], generation of terahertz (THz) electromagnetic waves by photomixing two wavelengths in a high speed photodetector [40] can be obtained among others.…”

“…Specially, dual-wavelength lasers have been widely developed for differential absorption light detection and ranging (LIDAR) [7], [8], microwave generation [9], [10] and spectroscopic dual-band OCT imaging [11]- [13]. Many different kinds of dual-band lasers have been proposed, but most of their schemes consist of two gain regions and a wavelength-selecting filter in the laser cavity [11]- [13].…”

Abstract-We report a simultaneous dual-band wavelengthswept laser based on the active mode locking method. By applying a single modulation signal, synchronized sweeping of two lasing-wavelengths is demonstrated without the use of a mechanical wavelength-selecting filter. Two free spectral ranges are independently controlled with a dual path-length configuration of a laser cavity. The static and dynamic performances of a dual-band wavelength-swept active mode locking fiber laser are characterized in both the time and wavelength regions. Two lasing wavelengths were swept simultaneously from 1263.0 to 1333.3 nm for the 1310 nm band and from 1493 to 1563.3 nm for the 1550 nm band. The application of a dual-band wavelengthswept fiber laser was also demonstrated with a dual-band optical coherence tomography imaging system.

“…Stable single-longitudinal mode (SLM) erbium-doped fiber lasers (EDFLs) are very important light sources for many applications, such as high-resolution spectroscopy, photonic generations of microwave signals, fiber sensing systems [1], and to create a dense wavelength division multiplexing (DWDM) back-up source with ITU-T grids [2]. However, the fiber ring laser unavoidably generates an enormous number of densely spaced longitudinal modes around the central lasing wavelength due to the associated intracavity optical components, connecting fibers, and a rather long cavity length.…”

In this article, the output power stability of several different highly erbiumdoped fiber ring lasers, as a function of the laser parameters, is experimentally investigated. The study is focused on the optimization of several key parameters (erbium-doped fiber length, pump power, and different laser configurations) without changing the basic scheme. The results obtained show that the laser configuration plays an important role in achieving stable multi-wavelength lasing at room temperature in the erbium-doped fiber ring lasers. For an optimized configuration, these power fluctuations are lower than 0.08 dB, showing a notable improvement compared with previously presented work where the output power variations were about 0.2 dB. These lasers have the advantage of a simple all-fiber configuration, low cost, high stability, and operability at room temperature.
