Latest Patents

Qin's latest patents include a "Method for generating femtosecond vortex beams with high spatial intensity contrast." This innovative method utilizes a noncollinearly pumped HG beam femtosecond laser to generate femtosecond HG beams, which are then converted into femtosecond LG vortex beams using a cylindrical lens mode converter. The design of the HG beam femtosecond laser includes a pump source, a gain medium, a saturable absorption mirror as a mode-locker, and an output coupler, allowing for the generation of pure, order-tunable femtosecond HG beams. The resulting femtosecond vortex beams exhibit high-intensity contrast and are topological charge-tunable.

Another notable patent is the "Method for generating ultrashort femtosecond pulses in optical parametric oscillator pumped by long pulses." This method focuses on managing dispersion and nonlinearity within the optical parametric oscillator. It involves forming linearly-chirped long pulses with broad bandwidth, which are then compressed to femtosecond pulses through second-order dispersion outside the optical parametric oscillator cavity. This technique enables the generation of ultrashort femtosecond pulses using long pulse pumping.
