Abstract
A laser diode package is provided, the package including a plurality of laser diode submount assemblies. Each submount assembly includes a submount. At least one laser diode is attached to a front portion of each submount while a spacer, preferably comprised of an electrically isolating pad and an electrical contact pad, is attached to a rear portion of each submount. Electrical interconnects, such as wire or ribbon interconnects, connect the laser diode or diodes to the electrical contact pad, either directly or indirectly. Preferably the laser diode stack is formed by electrically and mechanically bonding together the bottom surface of each submount to the electrical contact pad of an adjacent submount assembly. The laser diode stack is thermally coupled to a cooling block. Preferably thermally conductive and electrically isolating members are interposed between the laser diode stack and the cooling block.
