Abstract:
A laser diode array including a plurality of laser diode packages, each of said laser diode packages, comprising:a heat sink having an upper portion and a lower portion; a laser diode mounted to said upper portion of said heat sink; an electrically insulative substrate having a surface soldered to said lower portion of said heat sink by a substrate solder layer, said substrate having a width that is approximately a width of said heat sink, said width of said substrate being measured in the direction of the shorter of the two dimensions of said surface soldered to said lower portion of said heat sink; and an array solder layer on at least one of said heat sink and said laser diode, said array solder layer attaching said laser diode package to an adjacent laser diode package in said laser diode array, said array solder layer having a lower melting temperature than said substrate solder layer.
