A small core Yb³⁺-doped holey fibre laser and amplifier

Abstract

We have fabricated an ytterbium doped holey fibre with an effective area of just 2.5 μm² at the laser wavelength (1.03μm). Using this fibre, we have demonstrated a low threshold mode-locked laser using frequency feedback technique. Furthermore, by seeding with pico-joule femtosecond pulses, we obtain Raman solitons tunable from 1.06 to 1.58 μm.
