Abstract
The University of Central Florida invention is a thulium fiber geometry design specifically geared for in-band pumping. Thulium-doped fiber lasers have gained much interest recently in the field of directed energy because of the potential to create eye-safe sources at 2 µm. This design will take advantage of the higher efficiencies and lower thermal load of in-band pumping. The triple cladding design offers the best balance between thermal effects, modulation instability threshold and pump absorption. This geometry has the potential to provide greater than 5 kilowatts (kW) of continuous wave (CW) output power across the 1950-2100 nanometer (nm) region. Thulium-doped fiber lasers have gained much interest recently in the field of directed energy.
