“…In an earlier work, Zhou et al [10] have demonstrated a room-temperature all-fibre dualwavelength TDFL based on a cascaded fibre Bragg grating array. In this article, we develop a room-temperature all-fibre dual-wavelength TDFL operating near 1900 nm, which uses a simpler approach based on a spatial filter generated due to mismatch at the splicing points of a thuliumdoped fibre (TDF).…”

Abstract. We report a room-temperature all-fibre dual-wavelength thulium-doped fibre laser that operates around 1900 nm and uses a spatial mode-beating filter in a ring configuration. By pumping the gain medium with an 800 nm laser and controlling the phase mismatch at the splicing points of a thulium-doped fibre, the two output lines are obtained at 1844.8 and 1852.0 nm, with the corresponding signal-to-noise ratios of 30 and 21 dB. The threshold pump power is 109.3 mW. At the maximum pump power of 131.7 mW, the output powers are 0.297 and 0.038 mW for the 1844.8 and 1852.0 nm laser lines, respectively.

Abstract-A tunable dual-wavelength thulium doped fiber laser is demonstrated experimentally. For the first time for the 2-µm wavelength band we propose the independent tuning of the generated laser lines based on fiber Bragg gratings and the use of a Hi-Bi fiber optic loop mirror for the fine adjustment of the cavity losses to obtain stable dual-wavelength operation. Dualwavelength laser generation with the laser lines separation in the range from 0.3 to 6.5 nm is obtained. The laser emission exhibits an optical signal-to-noise ratio better than 56 dB. Improved stability with output power fluctuations less than 1 dB is observed in dual-wavelength generation with equal power of lines.

“…Up to date, there were many techniques have been proposed and demonstrated to achieve a dual-wavelength lasing such as by employing a dual-cavity configuration and twin-peak reflection grating. For instance, Zhou et al [12] demonstrated a room temperature all-fiber dual-wavelength TDFL based on cascaded fiber Bragg grating (FBG) array. However, the FBG structure requires an expensive UV laser to be fabricated and the conventional FBG cannot operate at temperature higher than 300…”

This paper describes the all-fiber dual-wavelength thulium ytterbium co-doped fiber laser by using a newly developed octagonal shaped double-clad thulium-ytterbium co-doped fiber as gain medium in conjunction with spatial filtering effect. The thulium ytterbium co-doped fiber laser operates at wavelengths of 1990.64 nm and 1998.92 nm with a signal to noise ratio of more than 34 dB as the 980 nm multimode pump power is increased above a threshold value of 1.5 W. The slope efficiency of the dual-wavelength laser is measured to be around 26.16%, which is comparable with the conventional thulium laser pumped by 800 nm single mode pump.
