Latest Patents

Geohegan's latest patents include a groundbreaking method for the growth of metallic films through a photoionization technique. This innovative approach involves heating a halide compound to produce vapor in a closed chamber, followed by irradiating the vapor with light of a specific wavelength. This process dissociatively photoionizes the vapor into positive ions and negative halogen ions, which are then subjected to an electric field for selective removal and plating as a film. Another significant patent focuses on enhancing the power output of pulsed laser systems. By injecting a minor amount of radiation energy just before the laser pulse, the efficiency of these systems is substantially improved, with the degree of enhancement depending on both the radiation wavelength and the time delay.
