Processes of dissipation and sensitization of electron excitation energy in erbium laser glasses

An experimental investigation was made of the laws governing nonradiative transfer of electron excitation energy in a system comprising Yb³⁺, Er³⁺, and Nd³⁺ rare-earth ions. Dependences of the parameters of elementary donor–acceptor interactions on the glass composition, and on the types of vitrifier and modifier were obtained.
