Abstract
An apparatus for adjusting the amount of laser light includes a laser light generator for generating laser light, and a detector for detecting the amount of the laser light so as to generate an output signal corresponding to the amount of the laser light. The apparatus further includes a first adjuster for adjusting the amplitude of the output signal and a second adjuster for adjusting the amount of the laser light generated by the laser light generator. The adjustment of the amplitude of the output signal and the adjustment of the amount of the laser light are performed separately through a selector.
