“…By now, several reports have treated ITO as a SA and inserted ITO into fiber lasers to realize Q-switched lasers or mode-locked lasers. Almost all lasers are emitted around the 1500 nm band [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. In 2020, Feng et al firstly reported that ITO-NWAs were employed as a SA in all-solid-state lasers and they realized passively Q-switched pulse lasers at 1.0, 1.3 and 2.0 μm [ 43 ].…”

We demonstrated a passively Q-switched Er:Ca0.8Sr0.2F2 laser with indium tin oxide nanowire arrays as an optical modulator in the mid-infrared region. In the Q-switched regime, the maximum output power of 58 mW with a slope efficiency of 18.3% was acquired. Meanwhile, the minimum pulse duration and highest repetition rate of the stable pulse trains were 490 ns and 17.09 kHz, corresponding to single pulse energy of 3.4 μJ and peak power of 6.93 W, respectively. To the best of our knowledge it was the first time that indium tin oxide nanowire arrays were employed as a saturable absorber to make pulse lasers carried out at 2.8 μm. The experimental data show that indium tin oxide nanowire arrays can be employed as a competitive candidate for saturable absorber in the field of mid-infrared solid-state lasers.

“…The prime approach is to employ the SA device. It has been employed successfully in different gain media [6,7]. The operation of mode-locking in 1, 1.5, and 2 µm wavelength regions has been achieved by the utilization of ytterbium-, erbium-, and thulium-doped fibers, respectively [8,9].…”

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

“…Active and passive Q-switching are two methods for achieving Q-switching [7], [8]. The active Q-switching method needs an extra device, namely, an electro-optic or acousto-optic device [1], [9], [10], whereas, the passive Q-switching method does not require those two devices. However, it does necessitate saturable absorbers (SA) that are cost-effective to manufacture and compact in size [11].…”

“…Simple fabrication [22], low cost [2], [10], easy to install [12], zero band gap [23], ultrafast recovery time [13], broad bandwidth [12], high damage threshold [18], [24], wide waveband absorption, and excellent electrical, optical properties [13] are some of the advantages of using carbon-based SAs. Due to its zero bandgap, graphene has a wider operating bandwidth than CNT [23].…”

A passively Q-switched erbium-doped fiber laser (EDFL) was experimented on by employing graphene, single walled carbon nanotubes (SWCNT) and multi-walled carbon nanotube (MWCNT) saturable absorbers (SA). The SA film was obtained by embedding the graphene, SWCNT and MWCNT into polyvinyl alcohol (PVA). The graphene SA was prepared by dipping a PVA thin film into the graphene solution while carbon nanotubes SAs were prepared using the casting method and placed in the ring cavity to produce a stable pulse laser. Graphene, SWCNT and MWCNT SAs were operating at wavelengths of 1558.92 nm, 1557.98 nm and 1558.51 nm, respectively, whereas the continuous wave was 1560.72 nm at the input pump power of 56 mW. The pulse energy, output power, repetition rate and pulse width were compared in graphene, SWCNT and MWCNT SAs. The shortest pulse width retrieved in graphene, SWCNT and MWCNT were 3.90 µs, 3.62 µs 4.43 µs and produced at the repetition rate of 115.00 kHz, 130.70 kHz, and 89.13 kHz, respectively. In comparison to graphene and SWCNT SAs, MWCNT SAs exhibit the best performance in terms of output power of 2.19 mW and high pulse energy of 24.57 nJ in passively Q-switched EDFL.
