摘要	In this work, we report a comparative study of the nonlinear optical responses of CH3NH3PbX3 (where X is a chlorine, bromine, or iodine halogen atom) perovskite thin (similar to 200 nm) films using 40 fs, 800 nm pulses. We found that these films possess strong nonlinear absorption coefficients comparable with the highest reported values for thin film structures (up to 7 x 10(-7) cm W-1). We also analyze the photoluminescence emission from CH3NH3PbBr3 film and demonstrate the quadratic dependence of emission intensity on the intensity of probe pulse indicating a two-photon mechanism of luminescence.
