- Аннотация: Absorption of continuous wave and pulsed resonance radiation at a wavelength of 1.6 µm at the upward transition from the excited state 5I7 of holmium (Ho 3+ ) ions in silica-based fiber has been studied. Analysis of experimental and simulated data of the absorption dynamics for the case of pulsed pumping of Ho-doped fiber allowed us to determine the previously unknown value of the absorption cross-section at the transition 5I7→5I5 as 1.9×10 –21 cm 2 . It allowed us to correctly simulate the relaxation process of the 5I7 level population averaged over the fiber length in the presence of stationary resonance radiation. The effect of pulsed resonance radiation with different peak powers (10 and 100 W) and pulse duration of 1 μ s on the stationary active medium was considered. The mutual influence of the Ho-doped fiber characteristics and the resonance radiation at a wavelength of 1.6 μm was found. This allows the resonance radiation to be used as an attenuator or modulator of laser radiation at the 5I8→5I7 transition in Ho-doped fibers.
