17 May 2011Temperature Raman laser sensor based in a suspended-core Fabry-Perot cavity and cooperative Rayleigh scattering
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.
