A wavelength-stabilized, semiconductor laser having a light amplifying diode heterostructure with a flared gain region in an external resonant cavity. The flared gain region has a narrow aperture end which may be coupled to a single mode waveguide and a wide output end. A light emitting surface of the...http://www.google.com/patents/US5651018?utm_source=gb-gplus-sharePatent US5651018 - Wavelength-stabilized, high power semiconductor laser
