Abstract
We report the application of a dual polarization distributed feedback (DFB) fiber laser as a strain and temperature sensor. By measurement of the abso lute wavelength of one polarization as well as the polarization beat freque ncy, strain and temperature were determined simultaneously. The sensor has an accuracy of +/- mu epsilon and +/-0.04 degrees C. Self-heating of the DF B fiber laser as a function of pump power was measured with this sensor.
