Paschotta, R., Moore, N., Clarkson, W.A., Tropper, A.C., Hanna, D.C. and Maze, G. (1997) 230 mW of blue light from a thulium-doped upconversion fiber laser IEEE Journal of Selected Topics in Quantum Electronics, 3, (4), pp. 1100-1102. (doi:10.1109/2944.649548).

Record type: Article


We demonstrate a powerful diode-pumped blue laser source, consisting of a 7W diode at 807nm that pumps a Nd:YAG laser giving 1.6W with good beam quality at 1123nm, and a thulium-doped upconversion fiber laser. The maximum output power achieved at 481nm is 230mW. We also describe the behavior of a reversible loss which is generated in the fluoride fiber during high power operation.
