Abstract
A method of controlling peak power of a radiant energy emitting system, such as lasers adapted for use in laser edge marking apparatus, reduces fog spots on the web caused by impinging laser energy. A laser printer has an attenuating member provided in the optical path of a laser beam tube for controlling peak power to each one of the plurality of lasers.
