Laser Diode Technology - Newport

Focusing the output beam of a laser diode into a single-mode fiber will also result in a circularized output. The fiber acts as a filter since only one mode propagates down the fiber. The output from the fiber is a circular, conical beam with a highly Gaussian shape, and low numerical aperture (N.A. 0.1).
