ABSTRACT:
A semiconductor laser device includes a heat sink having a plurality of element mounting portions, each having an element mounting surface and an insulator separating the element mounting portions from each other. A semiconductor laser element is arranged on each element mounting surface and a corresponding light receiving element for each laser element is disposed for monitoring the emitted laser light. External control circuits for adjusting the laser outputs of the respective laser elements are located outside the laser device package.
