Amplifier and laser of thulium-doped silica optical fiber

Abstract

espanolEn este trabajo se presenta un laser de fibra dopada con tulio en cavidad de anillo, operando en modo continuo. El bombeo se realiza en la zona de 1600 nm mediante laseres de fibra dopada con erbio. Se ha estudiado el comportamiento con bombeo en modo continuo y en modo pulsado, obteniendo unas eficiencias del 35% y del 38%, respectivamente. Estas eficiencias son superiores a las tipicas que se consiguen bombeando en 1600 nm. El laser emite en dos longitudes de onda separadas unos pocos nanometros, situadas entre 1910 nm y 1920 nm. Al mismo tiempo, se presentan tambien medidas de ganancia espectral de la fibra dopada con tulio. A modo de ejemplo, se ha realizado un amplificador de fibra dopada con tulio y se ha demostrado su viabilidad amplificando un espectro supercontinuo en la region comprendida entre 1800 nm y 2000 nm, el cual podria utilizarse para bombear fibras no lineales cuya longitud de onda de dispersion cero este situada en dicha region espectral. EnglishWe present in this work a thulium-doped fiber laser with ring cavity in continuous wave operation. The pumping is based on Erbium-doped fiber lasers at 1600 nm. The operation with continuous wave pumping and pulsed pumping has been studied, obtaining efficiencies of 35% and 38 % respectively. These efficiencies are higher than the known efficiencies pumping at 1600 nm. The emission spectrum has two peaks located between 1910 nm and 1920 nm. As the same time, we present measurements of the spectral gain of the thulium-doped fiber. As an example, we have implemented a thulium-doped fiber amplifier, demonstrating to be able to amplify a supercontinuum spectrum in the interval between 1800 nm and 2000 nm, which could be used to pump highly nonlinear fibers with a zero-dispersion wavelength in this region.
