Latest Patents

One of his latest patents is a "Single-shot pulse contrast measuring device based on non-harmonic long-wavelength sampling pulse." This device includes a long-wavelength sampling light generation unit, a large-angle non-collinear sum-frequency cross-correlation unit, and a high sensitivity signal receiving unit. The design allows for interaction of beams at a large non-collinear angle in a quasi-phase matching crystal, which helps eliminate scattered light noise. This innovation achieves single measurements of pulse contrast with a large temporal window and high dynamic range, making it suitable for measuring high-power lasers with various wavelengths.

Another notable patent is the "Method and system for detecting single-shot pulse contrast based on fiber array." This system features a correlator that generates a correlation signal, a spectral filter for light signal filtering, and a fiber array that transmits correlation signals in parallel. The design converts parallel correlation signals into serial correlation signals, which are then detected and processed to retrieve the single-shot pulse contrast. This method enhances the efficiency and accuracy of pulse contrast detection.
