Abstract

The saturation of the 2.71 micrometer laser in a 5000 ppm erbium doped ZBLAN single-mode fiber pumped at 791 nm was spectroscopically analyzed. 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. The saturation of the 2.71 micrometer emission is explained by co-lasing at 850 nm.
