摘要

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 62 X 10(7) Pa compared to the single mode counterpart. Good stability and repeatability of the sensor are also demonstrated.
