Abstract

A light source (8) and beam splitter (24) are connected with each other through a single mode optical fiber (14) cable so that a laser beam (B1) emitted from the light source is transmitted to the beam splitter through the single mode optical fiber cable, to be divided into a plurality of laser beams (B4). The respective laser beams emitted from the beam splitter are modulated by an acoustic-optical modulator (30), and then focused onto a photosensitive film (F).
