Title: The Innovations of Alvin Charles Erlandson
Introduction
Alvin Charles Erlandson is a prominent inventor based in Livermore, CA (US). He holds a total of 12 patents, showcasing his significant contributions to the field of technology and innovation. His work primarily focuses on advancements in optical systems and laser technology.
Latest Patents
One of Erlandson's latest patents is the "Gas cooled Faraday rotator and method." This invention aims to enable several orders of magnitude increases in average power and energy handling capability of Faraday rotators. The technology utilizes high-speed gas cooling to efficiently remove thermal loading from the Faraday optic faces while minimizing thermal wavefront and thermal birefringence by creating a longitudinal thermal gradient. A recirculating gas cooling manifold accelerates the gas over the surface of the slab to create a turbulent flow condition, maximizing the surface cooling rate. Furthermore, this technology provides a spatially uniform thermal profile on the Faraday slabs.
Another significant patent addresses the "Mitigation of the harmful effects of stray-light reflections in high-energy laser systems." This invention reduces or eliminates the negative consequences of reflected stray light from lens surfaces by propagating a laser beam through an eccentric pupil that excludes the optical axis of the system. By using an eccentric pupil, all damage due to focusing of the stray light lies outside of the beam, effectively preventing optical damage.
