Abstract

We report on a single-longitudinal-mode single-wavelength fiber laser and its applications for measuring localized temperature variation. The laser was developed using a fiber Bragg grating. The laser wavelength was single-longitudinal-mode with optical signal-to-noise ratio (OSNR) of more than 40 dB. The temperature sensitivity of the system was 11.08 pm/°C. To demonstrate the promising application of the laser sensor developed, we used the sensor to monitor the localized temperature of TiO₂ nanotubes during the photochemical process, and superparamagnetic iron oxides nanoparticles when exposed to low frequency magnetic field. The output of the laser was monitored using a scanning Fabry-Perot spectrum analyzer of resolution 6.7 MHz and an optical spectrum analyzer of resolution 3.75 GHz.
