Title: Innovations of John P Quitter in Laser Technology
Introduction
John P Quitter is a notable inventor based in Escondido, California. He has made significant contributions to the field of laser technology, particularly in the cleaning and passivation of laser discharge chambers. With a total of two patents to his name, Quitter's work has advanced the efficiency and safety of laser systems.
Latest Patents
One of Quitter's latest patents focuses on "Laser discharge chamber passivation by plasma." This invention provides methods and apparatus for cleaning and passivating laser discharge chambers using plasmas. In one embodiment, an oxygen-based plasma is created in a plasma source external to the laser discharge chamber by applying a radiofrequency signal to oxygen-containing gases. This plasma is then drawn into the 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. In another embodiment, the cleaning step with the oxygen-based plasma may be omitted, as some cleaning occurs with the fluorine-based plasma alone. Additionally, both oxygen and fluorine-based plasmas can be generated within the laser discharge chamber by applying a radiofrequency signal to the chamber's electrode. This innovative approach to plasma cleaning and passivation is deemed safer, more efficient, and more effective than traditional thermal methods.
