ABSTRACT:
A stepped-index optical fiber is disclosed for transmission of high-power radiation, especially laser, radiation, which fiber is capable of transmitting radiation without substantially impairment of the beam quality (of the beam product), can be bent with a specific radius, and wherein the cross-sectional area of the beam on the input coupling surface of the fiber can be very large. Formulae are presented for calculating the dimensions of the fiber.
