Title: The Innovative Contributions of Lelland A Weaver
Introduction
Lelland A Weaver is a notable inventor based in Pittsburgh, PA, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in laser technology, showcasing his expertise and innovative spirit in the field.
Latest Patents
One of Weaver's latest patents is the "Metal halide laser tube structure." This invention features a plurality of spaced-apart apertured discs made of electrical insulator material, which are sealed within the quartz tube structure of a metal halide laser tube. This design increases the path length along the wall of the laser tube between the discharged electrodes, effectively constraining the discharge to the central gaseous core rather than along the wall of the quartz tube. The use of these electrical insulator apertured discs enhances the utilization of halide species as the laser medium. Another significant patent is the "High power electrode and feedthrough assembly for high temperature lasers." This invention employs a double sealed technique in an evacuated quartz jacket, producing an electrical feedthrough assembly suitable for use in sealed-off, pulse, longitudinal discharge lasers. It is compatible with operating temperatures of up to 1100 degrees Celsius without oxidation and minimizes circuit inductance.
