Effects of the host glass on optical transitions
- Rutgers Univ., Piscataway, NJ (United States)
All the glass lasers consist of various rare earths doped singly or in combinations in different glass bases. Because the transitions are between energy levels with the same f-electron configurations that are shielded by 5s and 5p electrons from the ligand field, the fluorescent lifetimes are of the order of a few milliseconds and the ligand field interaction is of the order of a few hundred cm{sup {minus}1}. Nevertheless, the host glass has a substantial influence because of the site symmetry, the presence of multiple sites and the quenching associated with the interaction between the rare earth and the phonon spectrum of the glass. The use of fiber lasers for oscillators, amplifiers, and superluminescent sources will be discussed. The ions of particular interest are Er, Pr, Nd, and Tm.
