Graphic abstract: Thin films of MAPbI<sub>3</sub> and MA<sub>0.15</sub>FA<sub>0.75</sub>Cs<sub>0.1</sub>PbI<sub>3</sub> perovskites under femtosecond laser irradiation: nonlinear optical absorption and kinetics of photodegradation

Abstract: The thin MAPbI₃ and MA_0.15FA_0.75Cs_0.1PbI₃ perovskite films have strong nonlinear absorption with coefficients of 443 ± 20 and 830 ± 50 cm GW^–1, respectively, due to two-photon absorption at 1064 nm. The photochemical degradation of perovskite films was observed upon irradiation with femtosecond pulses at 532 nm, and the depth of photodegradation decreased in perovskite films protected with a PMMA polymer layer.

Keywords: organometallic halide perovskites, thin perovskite films, nonlinear optical absorption, femtosecond laser irradiation, photodegradation.
