title: Visible-NIR tunable Pr3+-doped fiber laser pumped by a GaN laser diode.
abstract: We demonstrated continuous wave laser operation with a tunable range of over 300 nm in the visible and near-infrared regions (479-497, 515-548, 597-737, 849-960 nm) using a single 9-cm Pr(3+)-doped ZBLAN fiber pumped by a GaN laser. The total tunable range was 6469 cm(-1), which is wider than that of conventional Ti:sapphire lasers.
