Multiphoton-pumped lasing from semiconductor nanocrystals in solution is difficult due to Auger recombination, low volume fraction and high threshold. Here, Li et al. demonstrate photostable, ultralow threshold multi-photon pumped lasing from colloidal CdSe/CdS nanoplatelets in a Fabry-Pérot optical resonator.
