Abstract
An apparatus for splicing, tapering and heat processing optical fibers is disclosed. The apparatus may include a laser configured to irradiate a portion of one or more optical fibers by at least two laser beams. The beams may be configured to irradiate different areas of the exterior surface of the fiber portion such as to increase the uniformity of heating distribution over the exterior surface of a portion of the optical fiber. In a configuration using two beams to irradiate the fiber portion the angle between the beams may be the closest angle to 180 degrees for which coupling between the first beam and the second beam is avoided. The apparatus may include three or more beams distributed around the optical fiber such as to irradiate the fiber portion uniformly and provide uniform heating of the fiber.
