Latest Patents

Zhen Qiao holds a patent for a method titled "Method for generating femtosecond vortex beams with high spatial intensity contrast." This method involves a noncollinearly pumped HG beam femtosecond laser that generates femtosecond HG beams. A cylindrical lens mode converter is then used to convert these beams into femtosecond LG vortex beams. The HG beam femtosecond laser consists of a pump source, a gain medium, a saturable absorption mirror as a mode-locker, and an output coupler. The unique configuration allows for the generation of pure, order-tunable femtosecond HG beams, resulting in high-intensity-contrast vortex beams that are topological charge-tunable.
