Special Issue Information

Dear Colleagues,

We are inviting submissions to this Special Issue on “Thulium-Doped Fiber Lasers—Advances and Applications”. 

Thulium-doped fiber lasers (TDFLs) have received great attention during recent decades, finding a wide spectrum of applications. In particular, the number of demonstrations of TDFLs generated at a wavelength range of 2 µm has increased rapidly in recent years. The gain bandwidth of Tm3+-doped silica fibers, ranging from 1.8 to 2.1 µm, makes TDFLs one of the most promising sources of mid-infrared coherent radiation for various applications, including medicine, spectroscopy, remote sensing, material processing, and frequency conversion. Due to the broadband gain bandwidth, thulium-doped fibers are also an excellent choice for an active medium in mode-locked fiber lasers and the generation of ultrashort pulses. Medical applications, especially soft-tissue surgery, can benefit from TDFLs operating at ~1.94 µm because of strong tissue absorption at this wavelength. The long-range propagation of laser radiation in the atmospheric transmission window around 2 µm can be address by using high-power, diode-pumped TDFLs. However, our topics of interest are not only limited to fiber lasers operating in the 2 µm spectral region, and reports on TDFLs utilizing other laser transitions are also invited.

This Special Issue of the Applied Sciences journal, “Thulium-Doped Fiber Lasers—Advances and Applications”, aims to present recent advances in the development of thulium-doped fiber lasers—different laser setups and generation regimes, including ultrafast mode-locked fiber lasers as well as high-power continuous-wave (CW) lasers, new designs of thulium-doped fibers, and their applications.

In this work, we compare the operation of a passively modelocked polarization-maintaining emission in two thulium-doped fiber lasers pumped at 1561 nm, with emission at wavelengths of 1.951 μm in one case and 2.07 μm in the other. We obtained a sequence of light pulses at 15.6 MHz, whose temporal width was 81 ps at 1.95 μm, and a sequence of light pulses at 13.1 MHz, whose temporal width was 94 ps at 2.07 μm. Finally, we also measured the long-term stability of this setup during a 24-h operation, as well as the short-term stability in a simulated harsh environment. The results confirm the superior performance of fiber laser systems with a fully polarization-maintaining design. Full article

In this paper, we have demonstrated a dispersion-managed, high-power, Tm-Ho co-doped ultrashort pulse fiber laser using a single walled carbon nanotube (SWNT) dispersed in polyimide film. An in-line type spectral filter was developed to control the output pulse spectra. Two SWNT films with different modulation depths were examined as a mode-locker. Normal dispersion fiber was used in the fiber laser oscillator, and dependence on net cavity dispersion was investigated. Passive mode-locking was achieved in a wide dispersion range, from −0.319 to +0.101 ps2. Stable soliton mode-locking operation and dissipative soliton mode-locking operations were observed. The pumping efficiency was ~3 times higher than that in a Tm-doped fiber laser with a similar configuration. The developed fiber laser showed self-start and stable operations, and this laser is useful for practical applications. Full article

We report a study on pulse dynamics in figure-nine Tm-doped all-polarization maintaining fiber laser. We analyzed laser operation from self-starting with multi-pulse dynamic to single-pulse operation by decreasing the pump power from the mode-locking threshold. By choosing a reliable setting of waveplates, our laser was generating pulses at the central wavelength of 1985 nm with a half-width of the spectrum, pulse duration, and pulse energy equal 6.4 nm, 650 fs, 177 pJ for the output port and 19.2 nm, 1279 fs, 57 pJ for the reject port in the single-pulse state. In the multi-pulse state, we recorded optical spectra, temporal waveforms, and average power at both exit ports. By analyzing temporal traces and output to reject port ratio power, we can distinguish between eight states of operation which follow an exact pattern. In the case of the single-pulse regime, we performed a further laser characterization, including relative intensity noise. Full article
