  • Publication number: 20240210785
    Abstract: Thermal lasers that emit narrowband, coherent infrared (IR), mid-infrared (MIR), or visible radiation with a tunable angle of emission are provided. The lasers include a metasurface that generates a lobe of narrowband, coherent thermal radiation at a desired frequency. The thermal radiation is coupled with an oscillating Fabry-Perot (FP) resonance mode of an FP cavity having an electrostatically or thermally adjustable reflection phase shift at the metasurface. This thermal laser design enables the steering of the lobe of emitted radiation continuously through a range of angles by modulating the phase shift at the metasurface.

  • Publication number: 20050043206
    Abstract: A composition of an aqueous, an aqueous acid, and an aqueous alkaline foaming additive (“foamer”) functions in a wide pH range and under conditions of salt, alcohol, and hydrocarbon contamination. The foaming additive (“foamer”) composition includes a mixture of a salt of an alkyl ether sulfate surfactant, a polymer or combination of polymers, and either a water miscible solvent for the liquid foamer additive or a silicon compound for a substantially anhydrous foamer additive.
