“…Including 50 m long SMF spool in the cavity increased net cavity dispersion which helped to achieve mode-locking instead of Q-switching [64,65]. A polarization controller (PC) was not added in this experimental setup as the interplay of cavity dispersion and the SA nonlinearity was sufficient to obtain mode-locking operation [66][67][68]. Hence, a PC was excluded from the experimental setup to avoid any additional insertion loss contribution from the PC.…”

A stable mode-locked laser was demonstrated using a newly developed zinc phthalocyanine (ZnPc) thin film as passive saturable absorber (SA) in ytterbium-doped fiber laser (YDFL). The ZnPc thin film was obtained using a casting method and then inserted between the two fiber ferrules of a YDFL ring cavity to generate mode-locked pulses. The resulting pulsed laser operated at a wavelength of 1034.5 nm having a repetition rate of 3.3 MHz. At pump power of 277 mW, the maximum output power and pulse energy are achieved at 4.92 mW and 1.36 nJ, respectively. ZnPc has a high chemical and photochemical stability, and its significance for use as a potential SA in a mode-locked laser is reported in this work. Graphical Abstract

“…[38,39] Recently, the family of MXenes and MAX-phases has been demonstrated to perform well as a SA to achieve ultra-fast fiber lasers. [40][41][42][43][44][45] A few other material categories have also been explored to produce Q-switched and mode-locked lasers, such as transition metal dichalcogenides, metals, transparent conductive oxides and organic materials. [8,[46][47][48][49][50][51][52][53] Furthermore, ternary transition metal dichalcogenides (TTMDs) have also recently gained the interest of researchers for ultrafast photonics.…”

In this work, we have demonstrated antimonene as a saturable absorber to generate ultrafast mode-locked and Q-switched laser at a 2-micron wavelength region. The two antimonene-based SAs were prepared and inserted separately in a thulium-holmium doped fiber laser (THDFL) to produce the pulsed lasers. Antimonene was coated onto the tapered fiber to generate soliton mode-locked pulses and in thin-film form for the generation of Q-switched pulses. The modelocking was stable within the pump power of 267 to 511 mW, and the laser operated at the center wavelength of 1897.4 nm. The mode-locked laser had a pulse width of 1.3 ps and a repetition rate of 12.6 MHz, with a signal-to-noise ratio (SNR) of 64 dB. The Q-switched laser operation was stable at the wavelength of 1890.1 nm within the pump power of 312 to 381 mW. With the increase in pump power from 312 mW to 381 mW, the repetition rate increased to a maximum of 56.63 kHz and the pulse width decreased to a minimum value of 2.85 μs. A wide range tunability of Q-switched laser was also realized within the wavelength of 1882 to 1936 nm.

“…To date, the mode-locked lasers are achieved by using various SAs, including but not limited to semiconductor saturable absorber mirrors (SESAMs), black phosphorus (BP), carbon nanotubes (CNTs), transition metal dichalcogenides (TMDs), topology insulators (TIs), MXenes and MAX-phases [21][22][23][24][25][26][27][28][29]. For instance, Wang et al [30] have demonstrated the generation of mode-locked laser and dynamics of soliton at 1.5 μm using a VSe 2 /GO-based saturable absorber.…”

Metal phosphates have emerged as low-cost inorganic materials suitable for high-performance energy storage and conversion devices. The photoluminescence properties of metal phosphates are now being explored for their optoelectronic applications. Among them, zinc phosphate is the composition of metal zinc and phosphoric acid. In this work, we have demonstrated the synthesis of zinc phosphate by the solvothermal method and its potential as a saturable absorber (SA) to generate a tunable mode-locked laser at 1.9 µm. Zinc phosphate was coated over arc-shaped fiber and incorporated in a thulium-holmium doped fiber laser (THDFL) to achieve the mode-locking. Soliton mode-locked pulses were achieved at a center wavelength of 1893 nm with the pulse duration, repetition rate, and signal-to-noise ratio (SNR) of 1.12 ps, 12 MHz, and 68 dB, respectively. The center wavelength of the mode-locked laser was tunable from 1893 to 1898.4 nm, and the pulse duration ranged between 1.12 to 1.4 ps. To the authors' knowledge, this is the first demonstration of a wavelength-tunable mode-locked laser using zinc phosphate as a SA at 1.9 µm.
