“…Moreover, the wide gain spectrum of the TDF makes TDFLs attractive for their application as widely tunable laser sources in optical instrumentation, microwave photonics, and terahertz generation at the 2 μm region. Several methods to obtain tunable laser emission in TDFL have been reported, where the wavelength tuning of the generated laser line is based on different fiber devices such as Hi-Bi FBGs [14][15][16][17][18][19][20], tunable filters [21][22][23], fiber optical loop mirrors (FOLMs) [24,25], and PCs [26][27][28]. In this regard, FBGs have proved their reliability as spectral filters for wavelength selection and tuning in fiber laser approaches.…”

Tunable dual-wavelength emission of a Tm-doped fiber laser based on two fiber Bragg gratings (FBGs) is experimentally demonstrated. By using two FBGs with central wavelengths at 2069.30 and 2069.44 nm, stable dual-wavelength laser generation in the 2 μm wavelength region is achieved by adjusting the differential loss of the two wavelengths in the laser cavity. Strain applied on the FBG allows independent tuning of the simultaneously generated wavelengths with separation between the laser lines in a range from 0.54 to 9 nm. The laser has output power fluctuations less than 0.093% for an output power of 77.3 mW.

“…Due to their huge potential for sensing applications, it is worthwhile to investigate the wavelength tuning of the TDFLs. So far, there are only few reports about the tunable TDFLs based on such devices as tunable Fabry-Perot filter [28], digitally programmable micro-mirror array [29], volume Bragg grating [30][31] and diffraction grating [32][33][34][35][36].…”

Two kinds of tunable Thulium-doped fiber laser (TDFL) respectively using a Sagnac loop mirror and a novel tunable multimode interference (MMI) fiber filter are experimentally demonstrated. The TDFL with the Sagnac loop mirror made by a 145.5-cm polarization-maintaining fiber (PMF) can operate with stable dual-wavelength lasing or tunable single-wavelength lasing around 1860nm. Both stable dual-wavelength and tunable single-wavelength lasing are achieved by adjusting a polarization controller in the Sagnac loop mirror. The TDFL with a novel tunable MMI fiber filter formed by splicing a segment of a special no-core fiber that is an all silica fiber without fiber core to single mode fibers can achieve tuning range from 1813.52 nm to 1858.70 nm. The no-core fiber with a large diameter of 200 μm is gradually vertically covered by refractive index matching liquid, which leads to a wavelength tuning of the transmission peak of the MMI fiber filter. The relationship between the refractive index of the refractive index matching liquid and the peak wavelength shift of the MMI fiber filter is also discussed. Using the MMI fiber filter, a Thulium-doped fiber laser with a tuning range of 45.18 nm is demonstrated.

“…This design involves only Tm‐doped fiber and fiber optical components, which greatly reduces system complexity and improves robustness, and operational reliability. In the previous study, we had used 793‐nm laser diode (LD) as the pump source in the Tm‐doped fiber laser (TDFL) . Then, the laser had a threshold pump power of ∼530 mW and generate over 35 mW continuous wave (CW) output power with 800 mW pump power.…”

We propose an all‐fiber source at 3.8 μm with a high Tm‐doped fiber as the gain medium pumped by a 1565‐nm high‐power fiber laser. With a laser diode at 1565 nm amplified by a high power erbium‐doped fiber amplifier injecting into a segment of Tm‐doped fiber, a fiber laser at 3.8 μm generates. Simultaneously, a second‐order laser at 1.9 μm (dual‐frequency of 3.8 μm) can be observed clearly. The laser has a threshold pump power of ∼300 mW and generates more than 176 mW continuous‐wave output power with 1560 mW pump power. © 2014 Wiley Periodicals, Inc.
