Abstract

The characteristics of the green (λ ∼ SSO nm) holmium upconversion fiber laser has been studied in detail in Ho:ZBLAN fibers ranging in length from ∼ 20 to 86 cm. When pumped in the red (∼ 643 nm), slope efficiencies up to 24% are observed for a 21 cm long fiber and a cavity output coupling of 30%. More than 38 mW of output power is observed for 280 mW of absorbed pump power. The influence of the depletion of the ground state (5Ig) population on the emission spectrum and overall efficiency of the oscillator are discussed.
