Certain Information from Luminescence Theory

Nonconducting solids (for example, single crystals) containing a small impurity of luminescent atoms are usually used as the active media for solid-state lasers. Such impurity luminophors can have a relatively narrow luminescence band; this is very essential, since the threshold pump power is proportional to the half-width of the luminescence band. Pure luminescent crystals are impractical active media because of their broad luminescent band (which arises because the transition is between energy bands) and also because of their excessively high absorption. In view of this, we shall restrict our examination to impurity luminescence.
