Abstract :
The beat spectrum of white spectral probe signals and a pump laser are used to directly give the Brillouin gain spectrum on an RF spectrum analyser. The measured peak gain coefficient is about 2.3*10-11 m/W and the Brillouin linewidth is 29 MHz which can be further broadened by the additional strain distribution.
