High-Visibility Pseudothermal Light Source Based on a Cr4+ : YAG Passively Q-Switched Single-Longitudinal-Mode Laser

الملخص EN

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 g2 value increased from 1.452 to 1.963.
