Abstract:
We demonstrate high-power operation from a singly Ho3+-doped silica fiber laser that is cladding pumped
directly with diode lasers operating at 1150 nm. Internal slope efficiencies approaching the Stokes limit
were produced, and the maximum output power was 2.2 W. This result was achieved using a low Ho3+-ion
concentration and La3+-ion codoping, which together limit the transfer of energy between excited Ho3+ ions.
