Abstract

In this work, a simple scheme for a temperature fiber laser sensor is proposed. The temperature laser sensor is based in the combination of a distributed mirror with a Fabry-Perot cavity. The distributed mirror is an outcome of the high Raman gain in the dispersion compensating fiber. The Fabry-Perot interferometer presents a double function, as one of the laser's mirrors and as the temperature sensing cavity. The proposed temperature laser sensor presents maximum output power of ~2.7mW while providing a temperature sensibility of ~6pm/⁰C, in a 200⁰C range.
