Polarization- and frequency-stable fiber laser for magnetic-field sensing.

We report a novel polarimetric fiber laser sensor for magnetic-field-current measurement that is stable to variation of temperature and strain because it employs a Faraday rotating mirror. We obtained a sensitivity of 10.24 kHzyA with good linearity and greatly improved the signal-to-noise ratio by reducing the number of laser cavity modes with the help of a saturable absorber.
