Abstract:

We have successfully developed a new technology of visible fiber laser, Pr-doped waterproof fluoro-aluminate glass fiber PrWPFGF laser. The significant achievements are as follows 1 greater than 1-W and multi-color visible fiber laser oscillations, 2 visible laser pulse generation in a Pr-doped waterproof fluoride glass fiber using a graphene thin film as a saturable absorber, 3 demonstration of a novel design of a simple and compact tunable visible fiber laser, and 4 for more high power operation,fabrication of a Pr-doped double-clad structured waterproof fluoride glass fiber with a single-mode beam. These results are very useful for scientific and industrial applications.
