Latest Patents

Horikoshi is credited with 1 patent, titled “Ultraviolet Laser Light Generation Device.” The invention describes a system that generates 399.08-nanometer ultraviolet light and uses it as the basis for producing 228.04-nanometer deep-ultraviolet light.

The device combines several optical processes. An excitation source converts 1064.2-nanometer laser light into 532.1-nanometer light. An optical parametric oscillator then produces 798.15-nanometer signal light and 1596.3-nanometer idler light. Wavelength-conversion components generate 399.08-nanometer light through sum-frequency generation and second-harmonic generation. A further conversion stage combines the 399.08-nanometer and 532.1-nanometer light to produce 228.04-nanometer output.

The patent presents a relatively simple device intended to generate deep-ultraviolet laser light efficiently, along with a 399.08-nanometer ultraviolet source that can serve as its foundation.
