Latest Patents

One of Da Li's latest patents is for a nonlinear optical crystal with a corrected phase matching angle. This invention allows for harmonic conversion using a source laser beam that only needs to be within a specific wavelength range, depending on the crystal's dispersion. The crystal is tilted to the calculated expected conversion angle, and the angle correction is achieved through a parallel kinematic motion device. This technology is applicable to both uniaxial and biaxial nonlinear optical crystals across a wide range of wavelengths, making it particularly valuable for crystals with large walk-off.

Another notable patent involves waveguide structures in anisotropic lasing and nonlinear optical media. This invention features a laser or nonlinear optical waveguide formed from a core anisotropic crystal, which is sandwiched between cladding crystals of the same material but with slightly rotated optical axes. The unique properties of anisotropic crystals allow for different refractive indexes, which are essential for effective mode confinement and single-mode operation.
