摘要： A wavelength resonant semiconductor gain medium is disclosed. The essential feature of this medium is a multiplicity of quantum-well gain regions separated by semiconductor spacer regions of higher bandgap. Each period of this medium consisting of one quantum-well region and the adjacent spacer region is chosen such that the total width is equal to an integral multiple of 1/2 the wavelength in the medium of the radiation with which the medium is interacting. Optical, electron-beam and electrical injection pumping of the medium is disclosed. This medium may be used as a laser medium for single devices or arrays either with or without reflectors, which may be either semiconductor or external.

摘要： An MFA-MOPA that includes a semiconductor laser with separate master oscillator and trumpet-flared power amplifier regions. Within the trumpet-flared active gain region of the uniformly-pumped power amplifier of the MFA-MOPA device, the density distribution of carriers and reflections of the laser beam are analyzed to determine the output powers at which filamentation and beam degradation due to reflections occur. The shape of the trumpet-flare is optimized to delay the onset of filamentation and the degradation of the output laser beam due to reflections to higher output powers for the MFA-MOPA device.
