description | Hybrid organic-inorganic perovskite shows a great potential in the field of photoelectrics. Embedding methyl ammonium lead bromide (MAPbBr<sub>3</sub>) in a mesoporous silica (mSiO<sub>2</sub>) layer is an effective method for maintaining optical performance of MAPbBr<sub>3</sub> at room temperature. In this work, we synthesized MAPbBr<sub>3</sub> quantum dots, embedding them in the mSiO<sub>2</sub> layer. The nonlinear optical responses of this composite thin film have been investigated by using the Z-scan technique at a wavelength of 800 nm. The results show plural nonlinear responses in different intensities, corresponding to one- and two-photon processing. Our results support that composites possess saturation intensity of ~27.29 GW/cm<sup>2</sup> and varying nonlinear coefficients. The composite thin films show high stability under ultrafast laser irradiating. By employing the composite as a saturable absorber, a passively Q-switching laser has been achieved on a Nd:YVO<sub>4</sub> all-solid-state laser platform to generate a laser at ~1 μm. |
