Latest Patents

Ping Xie holds a patent for "Four-fold and higher order continuous-wave upconversion lasers." This invention involves lasers that are pumped by multiphoton absorption, avalanche mechanisms, or other means of internal upconversion. The solid-state laser system is designed within an astigmatically compensated cavity, which contains first and second mirrors. The gain medium is formed from a crystal of lithium yttrium fluoride that is heavily doped with trivalent erbium. The crystal is approximately 3 mm thick and polished to a laser-grade finish. A pumping source provides energy at a wavelength of 1.5 µm, which is significantly longer than the output wavelength of 701.5 nm produced by the laser system. Additionally, the gain medium may also include an alkali vapor formed of Cesium or Rubidium.
