Abstract
A method for controlling a radiation intensity of a laser beam emitted by a laser having a threshold current level above which the laser emits the laser beam, the method including the steps of: supplying an electrical driving current for driving the laser, the electrical driving current increasing up to about the threshold current level; subsequently immediately further increasing the electrical driving current to a value above the threshold current level for causing the laser to emit the laser beam; and an image exposure device implementing this method.
