Latest Patents

One of his latest patents involves the use of plasma for cleaning and passivating laser discharge chambers. In this invention, an oxygen-based plasma is generated in a plasma source external to the chamber by applying a radiofrequency signal to oxygen-containing gases. This plasma is then drawn into the laser discharge chamber, where it reacts with contaminants to clean the internal surfaces. Following this cleaning process, a fluorine-based plasma is introduced to passivate the internal surfaces. This method is designed to be safer, more efficient, and more effective than traditional thermal cleaning and passivation processes.
