Latest Patents

Dongxia Qu holds a patent for a "Rotationally asymmetric chaotic optical multi-pass cavity." This invention relates to a specialized optical cavity that is useful in optical gas sensing spectroscopy, optical delay lines, and laser amplification systems. The design features a single closed mirror with a light reflective surface that is deformed in two orthogonal directions, specifically in the shape of a quadrupole in both horizontal and vertical planes. The cavity includes a light entry port and a light exit port, which may be the same or separate, along with a gas inlet and a gas outlet. The optical path length, beam divergence rate, and spot pattern can be controlled by selecting the cavity deformation coefficients and the input beam direction, allowing for the achievement of desired beam paths and beam quality. Dongxia Qu has 1 patent to his name.
