Abstract

Time evolution of the ⁵F₄⁵S₂ → ⁵I₈ fluorescence of Ho³⁺-doped zinc tellurite glasses was studied from 37 to 300 K. The time needed to achieve equilibrium between ⁵F₄ and ⁵S₂ states is 0.6 μs. Multiphonon relaxation from ⁵F₄, ⁵S₂ and ⁵F₅ levels of Ho³⁺ in zinc tellurite was studied. Two types of phonons were found to be effective. It is expected that at low temperature (37 K), laser emission, mainly from the ⁵S₂ level, will be obtained with a cross section of 2.78 × 10⁻²⁰ cm². Yet at room temperature laser emission from ⁵F₄ or ⁵S₂ can be obtained.
