High Performance, Spatially Coherent, Multicolor Distributed Feedback Lasers in Optically Pumped Colloidal Quantum Dots

Not Accessible

Your library or personal account may give you access

Abstract

Novel distributed feedback lasers were created in densely packed colloidal quantum dot single exciton gain media. The optically pumped lasers demonstrated internal efficiency of 28%, spatially coherent beams, average power of 400 µW.
