摘要：
Multiwavelength Brillouin Erbium fiber laser with ultra-narrow bandwidth filter is used as a temperature sensor. It has less than 10(-3) degrees C resolution at the 3rd-order Stokes in the short term. 3.104 MHz/degrees C sensitivity of the 3rd-order Stokes wavelength are demonstrated, which is three times that of the 1st-order Stokes wavelength. A less than 0.2 degrees C temperature error is obtained for every Stokes wavelength. This proposal can provide a feasible temperature sensing scheme with high sensitivity, high precision and low frequency detection.
