Figure 1.1.4 Energy levels and laser transitions of crystalline divalent lanthanide and actinide
ion lasers. The two energy level schemes for divalent samarium correspond to samarium ions in
different crystal field environments.

Figure 1.1.5 Energy levels, laser transitions, and wavelengths (microns) of crystalline cerium
and praseodymium ion lasers.
