  • UV-cure of coatings for an optical fiber with a laser
    Patent number: 7022382
    Abstract: An apparatus and method efficiently focuses laser light to a target fiber to rapidly and evenly cure a coating on the fiber and to increase a draw rate for the fiber. The laser light is expanded and refocused to a strip of light having a diameter that is a multiple of the fiber diameter. The strip of light is applied to one side of the fiber and a reflection of the strip of light is focused to a second side of the fiber to provide uniform radiation of the fiber.
