1.64 micron pulsed source for a distributed optical fibre Raman temperature sensor

Publication Date


This paper proposes a novel source for distributed anti-Stokes Raman temperature sensing. A source generating 8Watt, 10ns pulses at 500Hz at a wavelength of 1.64μm is demonstrated. Operating at 1.64μm enables the temperature dependent anti-Stokes signal at 1.53μm to be generated in the low-loss window facilitating a long range sensor.
