ABSTRACT:
A semiconductor laser device includes a semiconductor laser chip containing a diode having a polarity; a heat sink on which the semiconductor laser chip is mounted at an interface of the semiconductor laser chip and the heat sink, the heat sink including a pn junction generally parallel to the interface; and a block on which the heat sink is mounted, wherein the diode of the semiconductor laser chip and the pn junction are electrically connected in parallel and in opposite polarity so that the pn junction of the heat sink functions as a reverse current blocking diode for the semiconductor laser chip.
