Studies revealed that rare-earth doped glasses have a novel broad pumping band extending from 500 to 1000 nm that can efficiently excite rare-earth transitions. This excitation band gives a wide latitude in the choice of pump wavelength, and allows the excitation transitions in the mid-infrared with pumps in the red or near-infrared. Such devices only demonstrate the feasibility of host with low phonon energy as infrared sources. Chalcogenide glasses are another potential host for infrared sources because it also has low phonon energies. In addition to low phonon energy, they can also be fiberized, raising the possibility of fiber lasers operating in the 3-10 μm range and beyond.
