Todd C. Abel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Coherent, flexible, coated-bore hollow-fiber waveguide, and method of making same
    Patent number: 5567471
    Abstract: A rugged flexible hollow-fiber waveguide that permits preservation of good transverse spatial coherence of input infrared laser radiation and that transmits substantial power of such radiation, with low attenuation. The present invention preferably comprises a small-diameter thin-wall silica-glass tube; a protective coating on the outer surface of the tube; a sufficient reflective layer on the inner surface of the tube; and a thickness, optimal for the wavelength(s) of interest, of dielectric on the exposed surface of the reflective layer. The fiber is manufactured with processes that maintain the smoothness of the bore.
