Abstract of the Disclosure The effective modal reflectivity of angled antirefleetion-coated facets of a traveling-wave laser amplifier is significantly reduced by flaring the waveguiding portion of the amplifier in the immediate vicinity of the facets. In this way, low-reflectivity facets are achieved with simple low-cost antireflection coatings, thereby providing economical amplifiers characterized by wide bandwidth and high output saturation power.
