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.
