Latest Patents

One of Wu's latest patents focuses on extended lifetime frequency conversion crystals. This innovation addresses the issue of low lifetimes in solid-state lasers that utilize non-linear optical crystals for generating frequency tripled or quadrupled output in the ultraviolet spectrum. To mitigate damage to the crystal's face, Wu's design incorporates a controlled environment that remains free from contaminants. The crystal is housed within a tubular chamber, ensuring that harmful substances do not interact with the energetic photons of the ultraviolet output. The materials used for the chamber, such as sapphire or quartz for the windows and stainless steel for the walls, are chosen for their cleanability and durability.

Another significant patent by Wu is the electronic spotlight control system. This illumination system features optics that can adjust both the size and focus of a beam of light. The spot size control optics allow for adjustments in the overall size and ellipticity of the beam, while the focus control optics manage the beam's focus and astigmatism. Actuators, controlled remotely, facilitate these adjustments within the thermal environment of the illumination system, enhancing its versatility and effectiveness.
