“…To switch the wavelength, wavelength-selection and competitioninhibition mechanisms are needed. The wavelength can be selected with filters, such as the Mach-Zehnder interferometer [17] , cascaded Sagnac loop [18] , fiber-based Lyot filter [19] , micro fiber-optic Fabry-Perot interferometer [20] , few-mode fiber-based interferometer [21][22][23] and fiber Bragg grating (FBG) filters [7,24] . In particular, the FBG filter has been a good choice due to its simple structure, small size, and flexible tunability [25][26][27] .…”

A wavelength-switchable single-longitudinal-mode thulium-doped fiber laser using a sampled fiber Bragg grating is proposed in this study. The laser can be switched between three single-wavelength and three dual-wavelength modes of operation. For the single-wavelength mode of operation, the maximum power and wavelength fluctuations in 50 min were ±0.404 dB and ±0.01 nm, and the linewidths at three wavelengths were 0.39, 1.88, and 0.89 kHz, respectively. For the dual-wavelength mode of operation, the maximum power and wavelength fluctuations in 20 min were ±0.926 dB and ±0.03 nm, respectively. The proposed thulium-doped fiber laser will find useful application in optical communication and free-space optical detection and sensing.INDEX TERMS thulium-doped fiber laser, wavelength-switchable, narrow linewidth, sampled fiber Bragg grating.

“…Thus, how to achieve high stability, narrow linewidth, and wavelength flexibility with rapid wavelength tuning or selection are the key to successful deployment for thulium-doped fibers lasers (TDFL). The current tuning devices include fiber Bragg grating (FBG) [9][10][11][12][13], F-P cavity [14][15][16], Sagnac fiber ring [17,18], Lyot filter [19][20][21], Mach-Zehnder interferometer [22][23][24], liquid crystal spatial light modulator [25], digital micromirror device (DMD) [26][27][28], and so on. Up to now, a DMD chip as a semiconductor-based addressable micromirror array has drawn considerable attention due to its flexible and fast filtering functionality in optical switching, interconnecting, and lasers.…”

Wavelength-tunable thulium-doped fiber laser is demonstrated employing a digital micromirror device (DMD) in combination with a fixed grating. The diffraction property of four typical models of DMDs and its steering efficiency for the laser system are analyzed based on two-dimensional grating theory. By spatially modulating reflective patterns on a DMD, the stable, fast, and flexible tuning of lasing wavelength from 1930 nm to 2000 nm is achieved with wavelength tuning accuracy of 0.1 nm. The side-mode suppression ratio is larger than 50 dB around the 2 μm band with 3 dB linewidth less than 0.05 nm. The wavelength drift and power fluctuation are lower than 0.05 nm and 0.1 dB within 1 h at the room temperature, respectively.

“…In general, the wavelength-tunable TDFL could be realized by utilizing fiber Bragg gratings (FBGs) [11,12], volume Bragg gratings (VBGs) [13,14], diffraction gratings [15] Mach-Zehnder interferometer [16] and Fabry-Perot (F-P) filter [17]. In 2014, Liu et al reported a tunable dualwavelength TDFL based on a high birefringence fiber Bragg grating (HB-FBG).…”

In this demonstration, we proposed a novel wavelength-tunable thulium-doped fiber laser (TDFL) with a self-made Fabry-Perot (F-P) filter. When the F-P filter was not inserted, the maximum output power of 11.1 W was achieved when the pump power was 70.2 W. The corresponding optical-to-optical conversion efficiency was 15.8% and the slope efficiency was 22.1%. When the F-P filter was inserted, the output wavelength could be tuned from 1952.9 to 1934.9 nm with the change of cavity length of F-P filter which was fixed on a piezoelectric ceramic transducer (PZT) controlled by the voltage applied to it. The full width at half maximum (FWHM) was no more than 0.19 nm. Furthermore, the wavelength fluctuations of the tunable fiber laser were kept within ±0.2 nm.
