“…On the other hand, for passively mode locked fiber lasers, a mode locker is indispensable to sharpen the pulse in the temporal domain. The saturable absorber (SA) is a significant component of a passively mode-locked laser, which directly affects the improvement of pulse lasers' performance and hence has been considered to be a hot topic for ultrafast laser research in recent years [20][21][22][23][24][25][26]. Various SAs have been developed in past decades, and still, researchers are constantly exploring ideal SA materials with characteristics of safety, low cost, simple preparation methods, wide absorption band, high damage threshold, fast recovery time, and so on [23,[27][28][29][30][31][32][33][34][35][36][37][38][39][40].…”

Conventional solitons (CSs) as well as bound-state solitons in a passively mode-locked erbium-doped fiber (EDF) laser based on 1 T-phase titanium diselenide (1 T-TiSe 2 ) saturable absorber (SA) have been systematically demonstrated for the first time. The mode locker is assembled by sandwiching the 1 T-TiSe 2 film between two fiber ferrules to improve compatibility with the all-fiber-integrated ring cavity configuration. The modulation depth, saturation intensity and nonsaturable loss of the prepared 1 T-TiSe 2 SA are 14.36%, 1.33 MW cm −2 and 9.44%, respectively. The system is switchable between two states: CS and bound-state CS, by carefully adjusting the orientations of the polarization controller (PC). In the CS mode-locked regime, the oscillating wavelength is centered at 1558.294 nm with a pulse duration of 1.74 ps, a pulse repetition rate of 3.23 MHz and a maximum average output power of 2.904 mW. In the bound-state CS regime, two identical solitons form the bound-state pulses with a temporal separation of 6.1 ps, and the bound-state pulses are equally distributed at a repetition rate of 3.23 MHz, corresponding to the fundamental cavity repetition rate. The experimental results further indicate that 1 T-TiSe 2 SA is competitive with the existing SAs explored so far and will promote the applications of 1 T-TiSe 2 -based SAs in the field of ultrafast lasers.

Recent reports on thermal and thermoelectric properties of emerging 2D materials have shown promising results. Among these materials are Zirconium-based chalcogenides such as zirconium disulfide (ZrS 2 ), zirconium diselenide (ZrSe 2 ), zirconium trisulfide (ZrS 3 ), and zirconium triselenide (ZrSe 3 ). Here, the thermal properties of these materials are investigated using confocal Raman spectroscopy. Two different and distinctive Raman signatures of exfoliated ZrX 2 (where X = S or Se) are observed. For 2D-ZrX 2 , Raman modes are in alignment with those reported in literature. However, for quasi 1D-ZrX 2 , Raman modes are identical to exfoliated ZrX 3 nanosheets, indicating a major lattice transformation from 2D to quasi-1D. Raman temperature dependence for ZrX 2 are also measured. Most Raman modes exhibit a linear downshift dependence with increasing temperature. However, for 2D-ZrS 2 , a blueshift for A1g mode is detected with increasing temperature. Finally, phonon dynamics under optical heating for ZrX 2 are measured. Based on these measurements, the calculated thermal conductivity and the interfacial thermal conductance indicate lower interfacial thermal conductance for quasi 1D-ZrX 2 compared to 2D-ZrX 2 , which can be attributed to the phonon confinement in 1D. The results demonstrate exceptional thermal properties for Zirconium-based materials, making them ideal for thermoelectric device applications and future thermal management strategies.

“…Besides, in [19], the ring cavity is complicated, the operation is complexed and the compactness of the laser system is degraded because the existence of the free-space between the 1T-TiSe 2 SAM and the circular in the ring fiber laser regime. Comparatively, our total-fiber system presents a more compact construction, high stability and competitive output results with advantages of convenient maintenance and suitableness of practical applications [23].…”
