“…Tm 3+ is a favorable ion to produce 2-μm emission in fibers because of its high quantum efficiency, broad gain bandwidth, and strong absorption band around 800 nm, the wavelength available from commercial high-power diode lasers. Through the "two-for-one" cross-relaxation energy transfer, more than 70% slope efficiency has been reported in 790-nm pumped Tm 3+ -doped fiber lasers [1]. Furthermore, the broad gain bandwidth from 1.8 µm to 2.1 µm allows a large wavelength tuning range and makes Tm 3+ -doped fiber a suitable gain medium for femtosecond pulse generation.…”

We present the experimental investigation of a single-mode double-clad Tm 3+ -doped silicate fiber with ion concentration of 7 wt.% (8.35 x 10 20 /cm 3 ). A gain per unit length of 5.8 dB/cm at 1945 nm has been successfully achieved in a 3-cm Tm 3+ -doped silicate fiber amplifier, pumped with 647.6 mW at 1567 nm. To the best of our knowledge, this would be the highest gain per unit length reported for Tm 3+ -doped fibers. Furthermore, we experimentally demonstrate efficient cm-long fiber lasers and watt-level cladding pumped Tm 3+ -doped silicate fiber amplifiers.

We report on the development and testing of optical isolators for use in 2-micron fiber laser systems. A variety of potential Faraday rotator materials were characterised to identify the most suitable materials for use in the 1700-2100nm wavelength range. Isolators based on the three best performing materials were then developed and packaged as fiber-in, fiber-out and fiber-in, beam-out devices. The isolators were then tested in CW, pulsed and ultrafast laser systems. The three different designs produced different performance characteristics, but all designs demonstrated isolation >25dB and insertion losses of <1.2 dB.

“…Because the water vapor and some important greenhouse gas molecules in the atmosphere exhibit characteristic absorption lines around 2 μm wavelength region [1][2], TDFLs can be used in a wide range of applications, such as noninvasive surgery, remote sensing, laser radar, free-space telecommunications [3][4][5][6], etc. Many theoretical and experimental studies on TDFLs have been reported [7][8][9][10][11][12][13][14][15][16][17][18]. However, most of previously reported research mainly concentrated in high power [7][8][9][10][11] or pulse lasing [13][14][15][16][17][18].…”

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.
