Abstract

Abstract : High-visibility pseudothermal light source is required by the long-distance ghost imaging technology. In this article, the pulsed pseudothermal light based on a compact and Q -switched laser system with high peak power and intensity is reported. The passively Q -switched technique advances the performance of the pseudothermal light, where the second-order quantum correlation function g 2 value increased from 1.452 to 1.963.
