High-output performances lasers at 603 nm and 635 nm in Pr:ZBLAN fiber
In recent years, the Pr ion has gained great interest due to its vast spectral resources in the visible range. High slope and output power have been the focus of laser development in Pr-doped fibers. In this study, we investigated three different lengths of single-mode Pr:ZBLAN fiber with transitions of 3P0→3H6 and 3F2. The maximum output power of 204 mW and 555 mW were obtained with an optimum length of 23.5 cm and slope efficiencies as high as 65.4 % and 66.28 % at 603 nm and 635 nm, respectively. To the best of our knowledge, these are the maximum output power and slope efficiency at 603 nm and 635 nm in single-mode Pr:ZBLAN fiber pumped by blue laser. These results indicate the potential of single-clad Pr:ZBLAN fiber for visible laser operation with high output performances.
