Figure 1.1.2   Energy levels and laser transitions of crystalline titanium, vanadium, and chromium
                         ion lasers. The two energy level schemes for trivalent chromium correspond to chromium ions in
                         different  crystal  field  environments.  Dashed  levels  are  associated  with  laser  transitions
                         terminating on vibronic levels.
































                         Figure 1.1.3   Energy levels and laser transitions of crystalline manganese, iron, cobalt, and nickel
                         ion lasers. The two energy level schemes for divalent nickel correspond to nickel ions in different
                         crystal field environments. Dashed levels are associated with laser transitions terminating on
                         vibronic levels.
