Abstract:
1. A method of fabricating an optical fiber having a polished end face is provided, the method comprising: providing an optical fiber having an axis; positioning and maintaining the axis of the optical fiber, at a specific location along the optical fiber, at a fixed position; and forming a laser processed end face on the optical fiber at said specific location by irradiating the optical fiber at said location with one or more laser beams while moving the one or more laser beams in a rotational direction around the optical fiber, wherein the step of irradiating further comprises steering a laser beam and guiding the steered beam to said location along the optical fiber through a stationary optical system; and wherein the stationary optical system comprises an F-theta lens and a mirror array having a central axis, the mirror array having a parabolic profile about the central axis in planes through the central axis of the mirror array, and having a stepped profile in planes perpendicular to the central axis of the mirror array.
