Abstract
The possibility of developing 1.6μm band optical amplifiers was investigated using the emission from the Ho3+-doped cholcogenide glasses. Selenide and sulfide glasses with a low vibrational phonon energy were used as host materials. The maximum Ho3+ concentration in the glasses was 0.08mol% due to the cross relaxation process. Tb3+ co-doping reduced the lifetimes of the Ho3+:5I7 level and thereby, provided opportunities for the population inversion.
