| Abstract: | Fiber lasers in the visible spectral range at 603 and 634 nm were demonstrated using upconversion in fluoride Pr/sup 3+/-Yb/sup 3+/-doped fibers and Bragg gratings photoinduced in germanosilicate fibers. Reliable fine tuning of the all-fiber laser over 6.9 at 603 nm has been demonstrated using high strength fiber Bragg gratings. |
