  • Publication number: 20120281725
    Abstract: A laser diode system is disclosed in which a substrate made of a semiconductor material containing laser diodes is bonded to a substrate made from a metallic material without the use of any intermediate joining or soldering layers between the two substrates. The metal substrate acts as an electrode and/or heat sink for the laser diode semiconductor substrate. Microchannels may be included in the metal substrate to allow coolant fluid to pass through, thereby facilitating the removal of heat from the laser diode substrate. A second metal substrate including cooling fluid microchannels may also be bonded to the laser diode substrate to provide greater heat transfer from the laser diode substrate. The bonding of the substrates at low temperatures, combined with modifications to the substrate surfaces, enables the realization of a low electrical resistance interface and a low thermal resistance interface between the bonded substrates.
