Abstract

Based on the high photoluminescence quantum yield, broad absorption spectrum, and narrow symmetrical emission spectrum, perovskite quantum dots (QDs) have been adopted in pulsed laser generation as a saturable absorber, either organic or inorganic perovskites. In the paper, we improved the nonlinear absorption of CsPbBr₃ QDs by non-covalent doping of Au particles, and the nonlinear absorption properties of the prepared Au-doped CsPbBr₃ saturable absorber(SA) were characterized using the Z-scan system. A Q-switched laser output characteristics were obtained by building a Nd:YLF laser. We obtained a stable output average power of 815 mW and the minimum pulse width was 304ns. It shows that quantum dots can be modified to obtain better nonlinear coefficients by doping, showing potential application in the field of laser modulation.
