Abstract
Fibre-loop reflectors are applied to Nd3+ doped fibre lasers operating in the 4F3/2¿¿4I11/2 transition. The splitting ratio of the fused fibre coupler used in a loop reflector is varied thermo-optically, giving rise to a spectral variation in the reflectivity of the device. Using the fibre loop in a configuration with a broadband dielectric mirror to form a resonant cavity, we demonstrate wavelength tuning of the fibre laser and continuously variable power output for a constant pump power.
