Paper Abstract
An optimized 1.66μm Q-switched fiber laser is demonstrated for Raman-based distributed temperature sensor. In a ring
type Q-switched erbium-doped fiber laser, 850m TrueWave fiber is introduced to serve as both delay line fiber and
Raman gain medium so that in addition to the wavelength shifted to 1.6μm, the pulse duration and the buildup time can
be relatively extended. By properly controlling the fall edge of the acousto-optic switch, the pulse duration of 30-74ns
with peak power of 1.3-3.3W is achieved. Based on this light source, a 2.4km Raman-based distributed temperature
sensor is obtained with temperature resolution of 1°C and spatial resolution of 8m.
