Patent attributes
A laser diode assembly has a laser diode. The laser diode has an emitting surface and a reflective surface opposing the emitting surface. The laser diode has first and second side surfaces between the emitting and reflective surfaces. A first electrically-insulating heat sink is attached to the first side surface of the laser diode via a first solder bond, and the first heat sink has a first cooling channel. A second electrically-insulating heat sink is attached to the second side surface of the laser diode via a second solder bond, and the second electrically-insulating heat sink has a second cooling channel. A substrate has a top side and a bottom side, and the top side being in communication with a first bottom side of the first electrically-insulating heat sink and a second bottom side of the second electrically-insulating heat sink. The substrate has a flow channel system for passing a coolant to the first cooling channel and the second cooling channel. A metallization layer is attached to the first electrically-insulating heat sink and the second electrically-insulating heat sink. The metallization layer is electrically coupled to the laser diode and conducts electrical current to the laser diode. The metallization layer is isolated from the coolant.
