Latest Patents

One of Emmett's latest patents is for a multilayer optical dielectric coating. This highly damage-resistant coating includes alternating layers of doped and undoped dielectric material. The doping levels are low enough that there are no distinct interfaces between the doped and undoped layers, allowing the coating to maintain properties nearly identical to the undoped material. The fabrication process utilizes high-temperature plasma-assisted chemical vapor deposition techniques to eliminate defects and reduce energy-absorption sites. Additionally, he has developed tunable, rare earth-doped solid-state lasers. This laser apparatus combines an excimer pump laser with a rare earth-doped solid matrix, utilizing the 5d-4f radiative transition in a rare earth ion to produce visible and ultra-violet laser radiation with high overall efficiency.
