Fig. 9. Jablonsky Diagram for energy conversion pathways of an excited molecule. While fluorescence occurs between states of the same spin, an ISC (inter system crossing) leads to spin inversion and a delay in emission (phosphorescence halftimes from 1CT4 s to minutes or even hours)...

Figure 9.17 Simplified energy level diagram for Er33 showing the important up-conversion transitions (a) GSA and relaxation, (b) ESA and relaxation, (c) ESA and relaxation, and (d) emission of green and red. [GSA = ground-state absorption ESA = excited-state absorption. Spectroscopist s energy units (cm-1) are converted thus 25,000 cm-1 = 3.1 eV = 5.0 x 10-19J.]...

The development of up-conversion fiber lasers, especially in the visible, is assisted by the availability of intense semiconductor lasers and mini-crystal lasers for pump sources. The various energy levels involved in pumping and lasing transitions are detailed in Sec. 8.4 and in related energy level diagrams.
