CsPbBr3 perovskite quantum dots: saturable absorption properties and passively Q-switched visible lasers Download: 1109次
Abstract
This work presents the saturable absorption (SA) properties of CsPbBr3 perovskite quantum dots (QDs). The perovskite QDs show excellent SA performance with a nonlinear absorption coefficient of ?35×10?2 cm/GW and a figure of merit of 3.7×10?14 esu?cm. Further, their use as saturable absorbers in a passively Q-switched visible solid-state laser for the generation of soliton pulses is demonstrated. These results demonstrate the potential for the perovskite QDs to act as saturable absorbers.
