Measurement of Brillouin scattering coherence length as a function of pump power to determine Brillouin linewidth
Measurements of Brillouin scattering coherence length using a fibre Mach-Zehnder interferometer are presented. It is shown experimentally that the SBS lineshape narrows as the Brillouin pump power is increased from below to above threshold and that the coherence length approaches a limiting value.
