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 TiO~2~ 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. © 2010 Wiley Periodicals, Inc.

We experimentally demonstrate a ring-cavity, single-wavelength Brillouin-Raman fiber laser. An 11-km long dispersion compensating fiber was used as the medium for the Raman as well as the Brillouin amplification. A threshold power of 27 mW was recorded to get the Brillouin-Stokes line at 1455 nm pum
