Resonantly Pumped Amplification in a Thulium-doped Photonic Crystal Fiber

Not Accessible

Your library or personal account may give you access

Abstract

Efficiencies <50% are typical in large mode area, thulium-doped photonic crystal fibers when pumped at 790nm. These large thermal loads limit power scaling. In this work, we investigate resonant pumping and demonstrate slope efficiencies >64%.
