Abstract
The authors report a narrow linewidth, diode pumped, high power Q-switched erbium doped fibre laser for distributed temperature sensing applications using the Landau-Placzek ratio method. An output coupler consisting of an in-fibre Bragg grating enables narrow linewidth operation. A linewidth of 1.3 GHz is reported with a peak power of 100 W and a pulse width of 20 ns at a repetition rate of 200 Hz.Keywords
