Resumen:
Continuous-wave distributed-feedback (DFB) fiber lasers permits to achieve ultra narrow linewidths, although the average power tends to be low, typically in the mW range. The development of actively Q-switched DFB fiber laser with high peak powers and narrow linewidths is of interest for a number of applications and, particularly, for Brillouin sensor applications. Brillouin based temperature an strain distributed fiber sensors use either an external cavity diode or a DFB fiber laser, a pigtailed external modulator and a fiber amplifier in order to generate about 100 mW peak power pulses with a time width in the nanosecond range. Thus, actively Q-switched DFB fiber lasers are good candidates to be used in such an application, introducing an important lowcost simplification of the present arrangements.
