Abstract

As one approach to retrofitting a reprographic writing engine with a higher-power laser for direct-to-plate imagesetting, we developed a single-mode-fiber delivery for a Nd:YAG laser. The writing process required 4 W cw in a high-quality beam capable of high-speed modulation. We developed a laser of adequate beam quality and a fiber-coupling system that met the requirement with emission of 4 W cw at 1064 nm wavelength from a 5 micrometers -core fiber that had a 950 nm wavelength cutoff for the second mode.
