Abstract
Small diameter fibers formed from the use of laser energy and gaseous reactants and are disclosed. Also disclosed is an apparatus and method for the formation of continuous, substrate free, crystalline or amorphous fibers. Materials which can be formed into small diameter fibers include boron, silicon, germanium, zinc, tungsten, cadium, gallium, thenium, and compounds and mixtures thereof. The fibers have a diameter of about 10 micrometers to about 170 micrometers. The apparatus for producing the fibers includes a laser, a reaction chamber, and gas supply means. The laser beam has a focal point adjusted to coincide with the tip of the growing fiber, the focal point of the laser creating a region of elevated temperature at the fiber tip.
Claims9
A substrate free fiber consisting essentially of zinc selenide, said fiber having a diameter of about 10 micrometers to about 170 micrometers.
A substrate free fiber, said fiber consisting essentially of zinc selenide and having a diameter of about 10 micrometers to about 170 micrometers, wherein said fiber is formed by laser induced conversion of a vapor into a fiber having a minimum diameter determined by the diffraction limited laser focal spot size by the wavelength of the laser light.
