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