Laser-Induced Fluorescence. The fluorescence lifetime of a rare-earth-doped ceramic phosphor decreases with an increase in temperature. This relationship permits the fluorescence to be used in noncontact and remote temperature measurements. After a rare-earth-doped ceramic phosphor is excited by a delta-function excitation, electrons will be elevated from the valence band to the conduction band. The material fluorescence results from the energy released by electrons moving from the conduction band back to the original valence band.

A detailed understanding of our atmosphere, and of the various photochemical or collisional processes which determine the atmospheric composition, is of fundamental importance for mankind. Since in densely populated industrial areas air pollution has become a serious problem, the study of pollutants and their reactions with natural components in the atmosphere has become an urgent demand. Various techniques of laser spectroscopy can be successfully used in atmospheric and environmental research direct absorption measurements, laser-induced fluorescence, spontaneous Raman scattering, or coherent anti-Stokes Raman spectroscopy (CARS see Chap.9) can be utilized either for in situ measurements or for remote sensing.
