Abstract: We present in this paper the first demonstration of a Brillouin distributed sensor integrating a dual-frequency dual-polarization solid-state laser. This system allows the measurement of the Brillouin frequency shift at frequencies of hundreds of MHz which permits to benefit from balanced detection technique and highly sensitive electronics. The measurement results of a distributed Brillouin spectrum of two welded fibers are presented. The measured frequency shift as a function of temperature is in agreement with expected values.
