Abstract

The use of colloidal quantum dots (CQDs) as a gain medium in infrared laser devices has been underpinned by the need for high pumping intensities, very short gain lifetimes and low gain coefficients.

Keywords

colloidal quantum dots infrared lasers gain medium sub-single-exciton threshold high gain
