摘要：
In a semiconductor laser apparatus driving system, forward or/and backward beams from a plurality of semiconductor laser beam sources are detected, and arithmetic operations are provided for the detection outputs to determine the light outputs of the respective ones of the semiconductor laser beam sources. The use of a condenser lens which has been used in conventional system is eliminated and, as a result, precise positioning of such lens is avoided, and the semiconductor laser apparatus driving system can be mass-produced.
