Abstract
Amplification in Pr3+-doped fluorozirconate optical fibre is reported at the 632.8 nm He-Ne wavelength. Gross gains up to 11 dB have been achieved in a 1.4 m length using a launched pump power of 315 mW at 476.5 nm. Measurements of extinction at pump and signal wavelengths indicate that significantly improved performance can be expected using a much shorter length of fibre.Keywords
