摘要：

Strain sensing at the 10(-13) level, from the mHz to the kHz frequency range, is performed using a fiber Bragg-grating resonator interrogated by an optical-frequency-comb stabilized laser. The optical-comb synthesizer is a fs-pulsed fiber laser phase-locked to a quartz oscillator, which provides for a very high laser-frequency stability. The comb teeth span over the 1510-1580 nm spectral interval. Therefore, the OFS is also used as a coherent radiation source for fiber-loop cavity ring-down evanescent-wave spectroscopy of analytes diluted in liquid samples.
