Dual-wavelength single-longitudinal-mode erbium fiber laser for temperature measurements
Author(s): Silvia Diaz; Manuel Lopez-Amo

Paper Abstract

A dual-wavelength erbium fiber laser with single-longitudinal-mode characteristic is proposed and demonstrated. The system uses a 7-m-long highly doped erbium-doped fiber as the primary gain medium while two fiber Bragg gratings (FBGs) act as a wavelength selection mechanism. The sensing capability of the FBGs gives this source the possibility to be also used in a dual-sensor multiplexing scheme. The system is very stable and suitable for sensor multiplexing.
