Excited state absorption spectroscopy for thulium-doped zirconium fluoride fiber
چکیده انگلیسی

The excited state absorption (ESA) transitions at 1050 and 1420 nm play a fundamental role in thulium-doped fiber amplifiers (TDFA). We present a novel setup to measure the spectral cross-sections of these transitions in amplifier fibers and the results of this measurement in case of thulium-doped fluorozirconate (ZBLAN) fibers. Besides a standard system for fiber attenuation measurements and a long-pass filter, we use only components from the fiber amplifier setup, including the active fiber. No special parts are needed. We show that this fiber optic method delivers reliable results for different lengths of the doped fibers. The oscillator strengths of the measured transitions are calculated and compared to values published in the literature.
