This NASA SBIR Phase I proposal presents a novel method to achieve high emissivity, with a femtosecond (fs) fiber laser. It is the enabling technology for manufacturing high temperature, high strength, and high emissivity surface for electric propulsion components. With our successful history in laser processing, this proposal has a great potential to succeed. A proof of concept demonstration will be carried out and samples will be delivered at the end of Phase 1.Prototypes with various types of components in compliant with the NASA electric propulsion system requirement will be delivered at the end of Phase II.
In addition to NASA’s high emissivity surface manufacturing, the proposed short pulse high power fiber laser SM process can also be used in other applications, such as 3D printing, space vehicle, aircraft, and satellite manufacturing. PolarOnyx will develop a series of products to meet various requirements for commercial/military deployments.
