Abstract: This report describes 2 custom optoelectronic components for a 100-W continuous-wave erbium-doped fiber amplifier. The first is an interlock to protect the amplifier from damage resulting from too much light in the backward direction or too little light in the forward direction. The second is a device for measuring the optical power coupled from a pump diode to the pump combiner, using the light scattered at the splice between the 2 fibers.
