Abstract
An output control device for controlling the output of an electrical apparatus such as a laser in which a desired accuracy of control is maintained irrespective of the magnitude of the target value of the output. A first multiplication circuit multiplies the output indicating signal by a value which is dependent upon the reciprocal of the target value. The output of the first multiplication circuit is compared with a predetermined reference value to form a feedback signal having a component applied to control the output in such a manner that the absolute value of the difference between the output of the first multiplication circuit and the reference value tends to be decreased. A second multiplication circuit multiplies the comparison value output by the reciprocal of the output of the first multiplication circuit, and the resulting signal is applied to control the output of the electrical apparatus.
