Abstract

A method and corresponding apparatus for coupling an optical beam into a first end of an optical fiber includes two steps. First, light is coupled into a second end of the optical fiber such that an optical reference beam is output from the first end of the optical fiber. Second, at least one beam parameter of the optical beam is matched with the corresponding beam parameter of the optical reference beam. The second step may be performed using a wavefront sensor.
