Impurity ion energy levels in solid-state lasers

  1. Apr 8, 2016 #1
    1. The problem statement, all variables and given/known data
    I'm reading some text on solid-state lasers and a passage that struck me was this:
    "The low-lying energy levels of the ion are determined by the forces acting on and between the electrons in unfilled shells. (The electrons in unfilled shells can be regarded as inert.)"

    If I'm understanding this correctly, does that mean the energy level of E1, E2 can change in ions if there are large forces acting on the electrons in the unfilled subshells?

    2. Relevant equations


    3. The attempt at a solution
