Latest Patents

One of Spencer's latest patents is the "Transverse Flow Aerodynamic Lens." This invention describes a method and an apparatus for refracting a laser beam. The beam can be collimated, focused, or expanded as it passes through a series of in-line, orthogonally-mounted modules. Each module utilizes a fully-developed thermal boundary layer within a flow, between two cooled or heated parallel plates, to produce beam refraction. The laser beam traverses only fully-developed thermal boundary layers, generating parabolic density and refractive index profiles, which result in an undistorted gas lens. This gas lens can operate at high beam power densities, far exceeding the limits of conventional optical materials. Additionally, counter flow may be employed within each module to compensate for any streamwise index of refraction gradient, if necessary.

Another significant patent is the "Fluorine Generator for Chemical Lasers." This system generates fluorine for use as a gaseous reactant in a chemical laser from a storable gas supply of NF₃. This innovation enhances the efficiency and effectiveness of chemical lasers, making them more viable for various applications.
