Abstract

The spectroscopic properties of Fe2+:AgClxBr1-x crystals were investigated in the near and the middle infrared. Broad absorption bands were observed at low temperatures in the 1.3-2.5 μm range, and broad emission bands were observed in the 2.5-4.4 μm range. Luminescence lifetimes of up to 160 μs were measured at 3.6 μm. These results indicate that Fe2+:AgClxBr1-x crystals can be used as gain media for middle infrared solid-state lasers, operating continuously at 80 K. These doped silver halide crystals can be extruded to form optical fibers, possibly introducing another family of fiber lasers for this spectral range.
