Abstract

A fiber‐loop ring‐down spectroscopy based on multimode fiber is proposed for pressure measurement. It has been found that the multimode fiber‐loop ring‐down pressure sensor has higher sensitivity and larger dynamic range up to 6.2 Γ— 10^7^ Pa compared to the single mode counterpart. Good stability and repeatability of the sensor are also demonstrated. Β© 2007 Wiley Periodicals, Inc.
