Latest Patents

Earl R Ault holds a patent for the "CW Scalable donor-acceptor gas transfer laser." This invention involves a donor gas, such as helium or argon, which is pumped into a chamber with widely-diverging walls. The design allows for an expanded area at the delivery end. Electrodes mounted in the receiving end create a potential that excites the admitted gas into He₂⁺ or argon metastables. An arc discharge is produced for helium, while a glow discharge occurs for argon. The excited donor gas then flows through the chamber to a diffusion mixer formed by an array of nozzles. This mixer continually mixes the donor gas with an acceptor gas, such as nitrogen, supplied through the nozzles. The mixing results in an electronic excitation energy transfer reaction, where the charge from the excited donor is transferred to the acceptor. An optical resonant cavity communicates with the nozzle array, receiving the excited acceptor and generating a laser beam through population inversion in the cavity. The emission with nitrogen is a continuous wave in the UV-visible region.
