Quasi-one-dimensional (quasi-1D) transition metal chalcogenides (TMCs), a subclass of low-dimensional materials, have attracted significant attention due to their unique optical and electronic properties, making them promising candidates for nonlinear photonics. In this work, NbTe4, quasi-1D tetrachalcogenide, was synthesized employed the first time as broadband saturable absorber (SA) pulsed laser applications. The (NLO) properties NbTe4 were systematically characterized at 1.0 μm, 2.0 3.0 revealing saturation intensities 59.53 GW/cm2, 14 6.8 MW/cm2, with corresponding modulation depths 17.4%, 5.3%, 21.5%. Utilizing NbTe4-SA, passively Q-switched (PQS) pulses successfully generated in μm bands, achieving pulse durations 86 ns 2 μs, respectively. Furthermore, stable mode-locked operation demonstrated an Er-doped fluoride fiber yielding duration 19 ps. These results establish highly SA material next-generation ultrafast photonic devices pave way development other materials optics.
