摘要 |
There is provided a semiconductor laser apparatus capable of individually optimizing oscillations at a plurality of light emitting units fabricated on the single substrate in accordance with usages of each emitted laser lights. A plurality of cavities (laser diodes A and B), which correspond to the plurality of light emitting units, are fabricated on single substrate. And cavity lengths of the cavities are fabricated to different from one another.
