“…The TDF is also a prime choice in the development of tunable lasers as a result of its wide amplified spontaneous emission (ASE) spectrum from 1700 to 2100 nm. Furthermore, passively modelocked TDF lasers (TDFLs) are of particular interest [14][15][16][17] due to their significant applications in high-speed spectroscopy, sensing and biomedical research [1,6,8,18].…”

An ultrafast thulium-doped fiber laser (TDFL) with a wavelength tunable, passive mode-locked output is proposed and demonstrated. The TDFL employs a tunable Mach-Zehnder interferometer (TMZI) and a single-wall carbon nanotube (SWCNT)-based saturable absorber (SA). The TMZI provides the TDFL with a tuning range of almost 30.0 mm from 1919.4 to 1949.2 nm while at the same time maintaining the soliton output, with wavelength shifts of as small as 0.6 nm. The TDFL generates mode-locked pulses at a pump power of above 146.4 mW, and has a repetition rate of 9.1 MHz with an average minimum pulse width of 1.68 ps, as well as a maximum pulse energy and peak power value of 24.3 pJ and 13.0 W respectively. The mode-locked pulse is highly stable and has a relatively high signal-to-noise ratio value of around 56.0 dB. The use of the SWCNT-based SA is essential in generating the mode-locked pulses and the proposed laser has many potential uses in sensing and spectroscopy as well as in the generation of intense light sources for nonlinear optical applications.

“…optoelectronic countermeasure, environmental monitoring, medical, and coherent Doppler wind radars. Also, 2 µm lasers are efficient pump sources of optical parametric oscillators (OPOs) and optical parametric amplifiers (OPAs) for the generation in the 3-5 µm or 8-10 µm mid-wave infrared [6][7][8]. Therefore, researchers have been interested in the 2 µm solid state lasers.…”

A compact continuous wave and actively Q-switched Ho: YVO 4 laser pumped by a 1.94 μm Tm: YAP laser is demonstrated. The maximal output power of 4.32 W at 2052.9 nm in a continuous wave regime is obtained at an absorbed pump power of 18 W, corresponding to the slope efficiency of 32%. For Q-switch operation, 3.93 W output is achieved at a pulse repetition frequency of 9 kHz with a minimum pulse width of 21.3 ns at 2051.9 nm, corresponding to the slope efficiency of 30.9%. In addition, different pulse repetition frequencies of Q-switch operation with 9, 10, 20, 30, 40 and 50 kHz were investigated comparatively. Furthermore, this is the first time an experiment on the actively Q-switched Ho: YVO 4 laser has been published.

“…However, as a quasithree level system, the laser emission near 1.9 µm is difficult to obtain because of the reabsorption effect of the Tm ions. Although many Tm 3+ -doped crystals (YAG, YAP, YLF and LLF) [10][11][12][13][14][15][16][17][18][19][20] were studied in the past (shown in table 1) and several of them have shown good laser performance, only the Tm:YLF crystal [9] achieves efficient laser operation with a center wavelength near 1.9 µm. Compared with oxide crystals, fluoride crystals are interesting because of their lowphonon energy reducing non-radiative relaxation and making them particularly suitable for infrared (IR) transitions, lower refractive index limiting non-linear effects, high transparency within a wide wavelength region from the vacuum ultraviolet to the IR and longer fluorescence lifetime for improving energy storage [21][22][23][24].…”

Low-phonon PbF₂:Tm³⁺-doped crystal for 1.9µm lasing

Tm-doped PbF 2 crystal is successfully grown in a home-made Bridgman furnace. The laser properties of Tm 3+ in PbF 2 crystal at around 1900 nm are then evaluated based on the absorption and emission cross-section. Laser operation in Tm:PbF 2 single crystal at 1900 nm with laser-diode pumping is demonstrated for the first time. With a 2 mol. % Tm 3+ -doped sample, a maximum output power of 1.17 W is realized at a wavelength of 1900 nm for 6.8 W of absorbed pump power with a slope efficiency of 26%. We propose that the Tm:PbF 2 crystal may be a promising new material for 1900 nm high peak power laser applications.
