We review the state-of-the-art high power semiconductor lasers emitting at 0.98 and 1.48 μm, which are used for the pumping sources of the Er-doped fiber amplifiers. The introduction of strained-layer quantum wells to the active layer, together with graded-indexseparate-confinement-heterostructure enables us to improve the output power of semiconductor lasers. As a result, Er-doped fiber amplifiers with high signal output power are commercially available.
