“…DPs have a stable skeleton structure, and their features can be designed by choosing the right combination of elements and proportions . Due to the excellent electrical and optical properties of DPs, such as high internal quantum efficiency and strong linear and nonlinear absorption capacity, the application prospect of DPs in solar cells − and optoelectronic devices − (such as light modulators, photodetectors − and lasers , ) has attracted wide attention. Lead-free DP has the potential to become an environmentally friendly, structurally stable, and high-performance material for several reasons .…”

Lead-free double perovskites (DPs) have received a lot of attention owing to their good stability and environmental friendliness. They have been widely used in the field of optoelectronics because of their high quantum efficiency and long carrier migration distance. However, the application of leadfree DPs in ultrafast photonics is rarely explored. Cs 2 AgBiBr 6 , a typical lead-free double perovskite, has advantages such as toxicity free of Pb, high stability, and strong nonlinear absorption, showing great potential application in ultrafast photonics. However, to date, there is no reported research on the application of Cs 2 AgBiBr 6 in ultrafast optical devices. Herein, we prepared Cs 2 AgBiBr 6 nanocrystals, tested their ultrafast nonlinear absorption properties, and further prepared them as a saturable absorber (SA) to achieve stable mode-locking pulses in Er-doped fiber lasers. The results show that it has a low saturation intensity (0.75 MW/cm 2 ), resulting in a low starting threshold power (50 mW) for mode-locking. The obtained pulsed fiber laser shows a pulse width as narrow as 452 fs. In addition, the Cs 2 AgBiBr 6 SA has unique advantages in longterm stability and it was found that this Cs 2 AgBiBr 6 SA can still work well after 10 months. In general, our results prove that Cs 2 AgBiBr 6 is an excellent nonlinear optical material and has good application potential in ultrafast photonics.

“…In addition to 2D materials, many new-type low-dimensional nanomaterials as SA potential candidates have also attracted tremendous attention from the research community. For instance, the mode-locking pulse laser based on perovskite CsCu 2 I 3 microrods SA exhibits ultra-stable properties [ 33 ], and the PbS-SA-based EDF pulse laser can realize the switch between Q-switched state and mode-locking state [ 34 ]. Moreover, many artificial SAs have also been designed to generate mode-locked pulse lasers, which have outstanding pulse output performance.…”

The magnetic nanomaterial Mn3Si2Te6 is a promising option for spin-dependent electronic and magneto-optoelectronic devices. However, its application in nonlinear optics remains fanciful. Here, we demonstrate a pulsed Er-doped fiber laser (EDFL) based on a novel quasi-2D Mn3Si2Te6 saturable absorber (SA) with low pump power at 1.5 μm. The high-quality Mn3Si2Te6 crystals were synthesized by the self-flux method, and the ultrathin Mn3Si2Te6 nanoflakes were prepared by a simple mechanical exfoliation procedure. To the best of our knowledge, this is the first time laser pulses have been generated using quasi-2D Mn3Si2Te6. A stable pulsed laser at 1562 nm with a low threshold pump power of 60 mW was produced by integrating the Mn3Si2Te6 SA into an EDFL cavity. The maximum power of the output pulse is 783 μW. The repetition rate can vary from 24.16 to 44.44 kHz, with corresponding pulse durations of 5.64 to 3.41 µs. Our results indicate that the quasi-2D Mn3Si2Te6 is a promising material for application in ultrafast photonics.
