ABSTRACT:
A semiconductor laser apparatus in accordance with the present invention comprise: a semiconductor laser chip including a resonator with a couple of opposite end faces of which one is provided with an antireflective coating and the other with a highly reflective coating; a stem having a main surface to which the chip is attached with the end faces being vertical to the main surface; and a photoelectric conversion device, a major surface of which absorbs a part of a laser beam emitted from said one end face thereby to monitor intensity of the beam and reflects the remaining part of the beam for practical use.
