Abstract

A third-order process involving ligand excited states is discussed. We estimate that for two-photon absorption within the

f^{7}

configuration of

{Gd}^{3 +}

:Ca

F_{2}

this mechanism makes a contribution comparable to the third-order crystal-field process which has been used previously to explain the experimentally observed intensity distributions in that system.
