Abstract
This semiconductor laser apparatus includes a base, a plurality of electrodes arranged along a first direction on an upper surface of the base, a plurality of semiconductor laser devices bonded to respective upper surfaces of the plurality of electrodes, emitting laser beams in a second direction, and a photodetector having a photosensitive surface arranged in a region of the base in a third direction relative to the plurality of semiconductor laser devices. An electrode arranged in a position other than end portions in the first direction and a fourth direction, of the plurality of electrodes has an extraction wiring portion arranged on the photosensitive surface of the photodetector.
Claims20
A semiconductor laser apparatus comprising:
- a base;
- a plurality of electrodes arranged along a first direction on an upper surface of said base;
- a plurality of semiconductor laser devices bonded to respective upper surfaces of said plurality of electrodes, emitting laser beams in a second direction intersecting with said first direction;
- and
- a photodetector having a photosensitive surface arranged in a region of said base in a third direction opposite to said second direction relative to said plurality of semiconductor laser devices, wherein
- an electrode arranged in a position other than end portions in said first direction and a fourth direction opposite to said first direction, of said plurality of electrodes includes an extraction wiring portion arranged on said photosensitive surface of said photodetector.
An optical apparatus comprising:
- a semiconductor laser apparatus including a base, a plurality of electrodes arranged along a first direction on an upper surface of said base, a plurality of semiconductor laser devices bonded to respective upper surfaces of said plurality of electrodes, emitting laser beams in a second direction intersecting with said first direction, and a photodetector having a photosensitive surface arranged in a region of said base in a third direction opposite to said second direction relative to said plurality of semiconductor laser devices;
- and
- an optical system controlling laser beams emitted from said semiconductor laser apparatus, wherein
- an electrode arranged in a position other than end portions in said first direction and a fourth direction opposite to said first direction, of said plurality of electrodes has an extraction wiring portion arranged on said photosensitive surface of said photodetector.
