Abstract

Hybrid organic-inorganic methylammonium lead halide (CH₃NH₃PbI₃) perovskite with a direct band gap has emerged as a material in the development of optoelectronic devices. Here, for the first time, at.34~\mu \text{m}$ , we fabricated CH₃NH₃PbI₃ perovskite film saturable absorbers by spin coating methods for passively Q-switched Nd:YVO₄ laser. The CH₃NH₃PbI₃-SA shows a damage threshold of 276.6 mJ/cm², a modulation depth of 18.2%, and a considerably low saturation intensity of 140.7 KW/cm². By using CH₃NH₃PbI₃-SA, a stable Q-switched laser with a maximum average output power of 182 mW and a pulse width of 181.6 ns can be obtained. These results reveal the promising application of CH₃NH₃PbI₃ in 1.34 $\mu \text{m}$-lasers, optical switches or optical modulators.
