    Abstract

    The saturation of the 2.71 μm laser output power has been investigated in an erbium doped ZBLAN single-mode fiber with an Er3+ concentration of 5000 ppm mol. The bleaching of the ground state, the absorption coefficient at the pump wavelength and the fluorescence intensities over a wide wavelength range have been measured simultaneously during laser emission. In a computer simulation the rate equation system of the Er3+ system in ZBLAN fibers has been analyzed. The saturation of the 2.71 μm laser output is explained by simultaneous lasing at 850 nm.
