Abstract

Efficient amplification at around 0.8 µm in a monomode Tm³⁺-doped fluorozirconate fibre is reported. A gain of 23 dB at 805 nm was achieved for 50 mW of pump power at 780 nm. Low threshold (15 mW), high slope efficiency (>60%) laser oscillation in this wavelength region is also described.
