The resolution of strain measurements using Brillouin scattering in an optical fiber depends on the pulse width of a pump laser pulse. It was considered that there was a lower limit for pulse width, since the line width of the Brillouin spectrum was broader for shorter pulses. However, on the contrary, Bao et al. recently discovered a phenomenon in which the line width of the spectrum reduced with a very short pulse when there was light leakage. Such a result suggests the possibility that the resolution of a strain measurement can be improved. In this report, we analyze the phenomenon by solving coupled wave equations by a perturbation method and clarify the cause of the phenomenon. |
