Abstract
We report our developments of a 3-visible-wavelengths (Green, Yellow, Red) CW fiber laser system providing more than 3W of output power per colour on a single output path, in a simple and robust design. The system is based on three infrared narrow linewidth linearly polarized all-fiber lasers, combined into the same output PM fiber by a fused-fiber PM multiplexer. This component has been specially developed for the wavelengths of interest and to sustain high powers in CW operation. The common polarized infrared output is sent into a non linear optical stage to generate visible wavelengths, using periodically-poled non linear crystals and single-pass frequency doubling configuration. The system provides either 4W at 532 nm, 3W at 577 nm or 3.5W at 633 nm with a perfect beam quality and a free-space output.
