![]() Since then, inspired by graphene, 2D materials, including transition metal dichalcogenides (TMDs), ,, ,, ,, ,, ,, topological insulators (TIs), ,, ,, ferromagnetic insulators, ,, metal chalcogenides, , MXenes, ,, ,, , and group Ⅳ to Ⅵ Xenes (graphdiyne, phosphorene, ,, ,, ,, ,, ,, antimonene, , bismuthene, ,, silicene, , and tellurene ), have been employed to propose ultrafast SAs with excellent absorption performance successfully. Specifically, since its first ultrafast application in 2009, , graphene has been widely employed as SA to demonstrate pulsed laser operations and regarded as a recognized pathfinder for the investigation of 2D material-based ultrafast optoelectronic devices, ,, ,,. Especially, two-dimensional (2D) material-based SAs exhibit tremendous development potential and practical application prospects due to its excellent 2D material-related properties, including wide absorption band, ultrafast recovery time, high damage threshold, and low cost. Recently, ultrafast saturable absorbers (SAs), including mode lockers and Q-switchers, have been extensively investigated to demonstrate pulsed laser operations, ,, ,, ,, ,,. Our contribution reveals the great potential and capacity of tellurene-based SAs in obtaining large-energy pulse operations and further promotes the explorative investigation of Xenes-based optoelectronic devices. NLP operation with a recorded average output power of 106.6 mW and a pulse energy of 8.76 nJ is also generated, which shows significant enhancement in comparison to previously reported Xenes-based works. ![]() For DS operation, the maximum average output power, pulse width, and largest pulse energy are 23.61 mW, 5.87 ps, and 1.94 nJ, respectively. In this work, we focus on the preparation of tellurene-based SAs and explore its applications in demonstrating large-energy mode-locked operations. However, tellurene-based SAs to demonstrate large-energy mode-locked operations, which have special applications in industrial and scientific research areas, are seldom studied. ![]() Few-layer tellurene as a typical Xenens exhibits distinct optoelectronic properties and promising practical application potential, and its nonlinear optical absorption characteristics and related ultrafast modulation applications have been investigated preliminarily. Xenes also show excellent performance in acting as saturable absorbers (SAs) for obtaining ultrafast laser operations. Two-dimensional layered monoelemental materials (Xenes) with excellent optoelectronic properties have various property-related applications, such as energy, biomedicine, and optoelectronic devices.
