Perovskite quantum dot one-dimensional topological laser

Topological lasers often suffer from low directionality, and/or complex design requirements hindering operation at small wavelengths. Here, by using a few monolayers of perovskite quantum dots, the authors demonstrate a lithography-free, vertical-emitting, single-mode laser emitting in the green.
