Title: Innovations and Contributions of David B Cohn
Introduction
David B Cohn, based in Torrance, CA, is a prolific inventor with an impressive portfolio of 20 patents. His work predominantly focuses on advancements in laser technology, particularly in enhancing gas flow systems and catalyst configurations for improved efficiency and performance.
Latest Patents
Among his latest patents, one innovation involves an array of discrete catalyst elements contained in a heated module external to the main laser vessel. This design includes an auxiliary gas flow loop that allows for the independent control of catalyst temperature and gas flow rate, facilitating high CO + 1/2O to CO recombination under high pulse repetition frequency operation for a sealed laser. The catalyst elements, designed in the form of cylinders with holes through their centers, are mounted on multiple parallel rods. This configuration minimizes flow impedance and maximizes laser gas recycling throughput. The cylindrical catalyst module is engineered for rapid heating to operating temperature while withstanding atmospheric differential pressures during laser processing.
Another notable patent describes a CO gas flow laser that incorporates multiple discharge modules. It strategically places acoustic baffles between these modules to suppress shock waves and ions that may disrupt the laser's optical path. Additionally, the design may include a catalyst situated in the center of a toroidal recirculation chamber, equipped with integrated filters to prevent catalyst particulates from coating the chamber's optical windows.
