Abstract

Nonlinear optical characteristics of single-crystalline CsPbCl3perovskite microcavities under multiphoton excitation are studied. The high 3-photon absorption coefficient of the clusters of CsPbCl3microplates is found to be 2.1 × 10-5cm3GW-2for the support of low-temperature amplified spontaneous emission. Furthermore, stable lasing emission is observed from single CsPbCl3microplates under 3-photon excitation at 83 K. Hence, we have shown that single-crystalline CsPbCl3perovskite semiconductor microstructures have excellent nonlinear optical properties for the realization of novel upconversion lasing devices.
