Stimulated Emission and Lasing from CdSe/CdS/ZnS Core‐Multi‐Shell Quantum Dots by Simultaneous Three‐Photon Absorption

Abstract

Three-photon pumped stimulated emission and coherent random lasing from colloidal CdSe/CdS/ZnS core-multishell quantum dots are achieved for the first time. These results can offer new possibilities in biology and photonics, as well as at their intersection of biophotonics.
