  • Emitter array with individually addressable laser diodes
    Patent number: 6348358
    Abstract: A linear array of diode laser emitters is manufactured with sufficient thermal and electronic isolation among the emitters to permit separate addressability. The emitter bar has first and second opposed surfaces and a third surface through which the emitters direct output. A first surface of the emitter bar is affixed to a “standoff” element that has conductive surfaces connecting each emitter to a power source; these connections are maintained after a series of spaces is formed between the emitters of the emitter bar. The second surface of the emitter bar is affixed to a heat sink to form a finished assembly.

  • Pumped laser diode assembly with optically coupled heat sink
    Patent number: 6222870
    Abstract: Individually addressable laser crystals are optically coupled to a single slab of an optical carrier that transmits substantially without distortion. The crystals are separate for thermomechanical isolation but may be closely spaced (generally on the order of 0.003 inch apart), and may originate as a single crystal cut into separate segments.
