Latest Patents

One of Fan Gao's latest patents is the "Beam optical axis self-stabilizing device and method based on reflection mechanical modulation." This invention provides a device that includes a polarized beam splitter, a quarter-wave plate, a structural reflecting element, and a driving source. The quarter-wave plate is positioned at the output end of the polarized beam splitter, while the reflecting element is located on the side of the quarter-wave plate that is away from the polarized beam splitter. The driving source rotates the structural reflecting element at a uniform speed, allowing incident light to pass through the polarized beam splitter and obtain split light. The split light then passes through the quarter-wave plate to enter the structural reflecting element, which rotates to vary the phase of the reflected light over time. The reflected light is modulated by the quarter-wave plate and emitted through the polarized beam splitter, resulting in a target beam.

Another notable patent is the "High-efficiency high-power ring laser amplifier." This invention consists of four polarizers, four amplifiers, four lenses, two filter apertures, two electro-optic switches, a mirror, and a wavefront corrector. The bidirectional ring laser amplifier configuration with twin pulses is adaptable to various types of gain media and pumping configurations. This amplifier configuration significantly improves the extraction efficiency of the gain medium. The proposed amplification configuration can achieve ring amplification for any number of rounds and effectively control the quality of the output laser beam while relaxing the restrictions on injected energy. The two spatial filters in this high-efficiency high-power ring laser amplifier effectively remove spatial modulations in the laser beams, with the first and second spatial filters reimaging the beam at the wavefront corrector to the mirror, which inhibits diffraction effects.
