LOW SIZE AND WEIGHT, HIGH POWER FIBER LASER PUMP

摘要

A device for cooling a laser diode pump comprising a Low Size Weight Power Efficient (SWAP) Laser Diode (LSLD) assembly, including a laser diode coupled to a submount on a first surface, the submount comprising a first thermally conductive material and a heatsink coupled to a second surface of the submount, wherein the heatsink comprises a second thermally conductive material, the heatsink comprising one or more members formed on a side opposite the coupled submount. The device further comprising a housing coupled to the LSLD assembly, the housing comprising a carrier structure having an aperture configured to support the LSLD assembly on a first side and having a plurality of channels on a second side, a bottom segment configured to couple to the carrier segment to create an enclosure around the channels between a top side of the bottom segment and the second side of the carrier structure, an inlet and outlet formed in the housing for transporting a coolant into and out of the channels in the enclosure, wherein the members are disposed within the enclosure so as to expose the members to the coolant.
