Abstract

Lead-free halide perovskite nanomaterials have aroused enormous attention and have been employed in many optoelectronic devices depending on their outstanding optical properties, especially their intrinsic stability. Regarding ultrafast fiber lasers, their high stability and low cost are crucial aspects of their industrial and scientific application. Thus, the high stable CsCu₂I₃ micro-rods are an ideal candidate for Saturable Absorbers (SA) in fiber laser systems. Herein, a passively mode-locked erbium-doped fiber laser based on CsCu2I3-SA was demonstrated operating at the communication band. To the best of our knowledge, the fiber laser could operate stably for over 164 days. These experimental results demonstrate that the CsCu₂I₃ micro-rods are ultra-stable and a promising optical modulation material to produce an ultrafast and long-stability pulse in fiber laser application.
