What Is a Nanolaser?

Nano-laser refers to a micro-nano device that uses nano-materials such as nano-wires as a resonant cavity to emit laser light under light or electrical excitation. The size of such lasers is often only hundreds of microns or even tens of microns, and the diameter is even on the order of nanometers. It is an important part of future thin film display, integrated optics and other fields.
