Abstract
We analytically investigate the case of the Brillouin interaction between probe waves propagating against two modulated pump waves. This investigation is motivated by the sweep-free BOTDA technique, where, to increase the BOTDR sensing speed, the Brillouin gain spectrum is simultaneously interrogated by many probe-pump pairs. It is shown both analytically and experimentally that the Brillouin interaction between a probe and its corresponding pump is negligibly affected by a neighboring pump only when the pump tones separation is much larger than the width of the Brillouin gain spectrum.
