Abstract :
The authors propose a novel source for distributed anti-Stokes Raman temperature sensing. A source generating 8 W, 10 ns pulses at 500 Hz, at λ=1.64 μm is demonstrated. Operation at 1.64 μm enables the temperature dependent anti-Stokes signal at 1.53 μm to be generated in the low-loss window, facilitating a long range sensor
