Brillouin based distributed fibre sensor incorporating a mode-locked Brillouin fibre ring laser

摘要

A pulsed Brillouin fibre ring laser has been developed and we describe its main features. The pump and the Brillouin laser are shown to form an excellent dual frequency source for distributed sensing. A first application for fire detection is demonstrated. (C) 1998 Elsevier Science B.V.
