“…The pulse width obtained was lower than many of the previously reported single-regime Q-switched operation using graphene-PVA based Sas, and it was comparable to the one employing a graphene-silica hybrid waveguide and optically deposited graphene oxide [ 32 , 33 , 34 ]. It was also lower than those reported using MXenes and MAX phase [ 35 , 36 , 37 , 38 , 39 ]. The calculated instantaneous peak power and pulse energy was observed to follow the upward trend in which the peak power and the pulse energy maxed out at 53.3 mW and 82.08 nJ, respectively.…”

“…The calculated instantaneous peak power and pulse energy was observed to follow the upward trend in which the peak power and the pulse energy maxed out at 53.3 mW and 82.08 nJ, respectively. The recorded pulse energy is higher than the one reported using SWCNT SA via evanescent field interaction as well as MXenes and MAX phases [35][36][37][38][39]. A high SNR of 57 dB was obtained at the maximum repetition rate of 88.97 kHz, as shown in Figure 11, wherein no changes or drifts were observed in the spectral widths and frequency stability, indicating high laser operation stability.…”

We investigate the dynamics of high energy dual regime unidirectional Erbium-doped fiber laser in ring cavity, which is passively Q-switched and mode-locked through the use of an environmentally friendly graphene filament–chitin film-based saturable absorber. The graphene–chitin passive saturable absorber allows the option for different operating regimes of the laser by simple adjustment of the input pump power, yielding, simultaneously, highly stable and high energy Q-switched pulses at 82.08 nJ and 1.08 ps mode-locked pulses. The finding can have applications in a multitude of fields due to its versatility and the regime of operation that is on demand.

In this work, we proposed a mechanical exfoliation technique to compose a saturable absorber (SA) from MAX phase chromium aluminum carbide (Cr2AlC). The performance of a passive Q‐switched erbium‐doped fiber laser (EDFL) based on Cr2AlC‐SA was experimentally demonstrated. The optical properties of SA showed appropriate nonlinear absorption, with a non‐saturable absorption of 92.5%, and saturable absorption of 1.2%. The proposed EDFL was investigated using 50:50 and 80:20 output couplers (OCs). At 167 mW pumping power and 3 dB OC, the EDFL produced pulses with 2 μs width, and 163 kHz repetition rate. Moreover, with 80:20 OC, the EDFL produced shorter laser pulses with 1.46 μs width, and 135.2 kHz pulsing rate. The results reveal that the higher repetition rate with high energy can be obtained with a 3 dB coupler, while narrower pulse width is achieved with an 80:20 OC.

Recently, the research in MXene-based SAs has gained extensive attention due to their excellent nonlinear optical properties [1,[14][15][16]. The general formula for the MXene is Mn+1XnTx, where M represents the 2D transition metal, X represents carbon or nitrogen, and T belongs to the face termination element, including hydroxyl, oxygen, or fluorine, with x denotes the number of terminal groups.…”

A new MAX-phase-based saturable absorber (SA) known as Titanium Aluminium Carbonitride, Ti3Al(C0.5N0.5)2 PVA composite film is successfully developed to demonstrate a reliable Q-switched laser in the 1.55-micron region. The Ti3Al(C0.5N0.5)2 composite film with a size of about 1 mm2 is sandwiched between two fibre ferules and integrated into an erbium-doped fibre laser (EDFL) ring cavity. The film SA has a linear absorption of about 5.7 dB at the pulsing region, and a modulation depth of 21%. The Q-switched laser, which is centred at 1561 nm, stably appears at a pump power range of 25 mW-55 mW. The Q-switched laser has the highest repetition rate of 46.3 kHz and the narrowest pulse width of 6.6 µs. The maximum calculated peak power is 1.6 mW, while the highest pulse energy is 10.54 nJ. This demonstration suggests that the Ti3Al(C0.5N0.5)2 can be an alternative SA that may have a good prospect in optical-related applications.
