Abstract
Two-photon absorption phenomena are useful for the generation of short wavelength radiation. When the same atom absorbs IR and visible photons it generates uv/visible energy. Such two-photon absorption phenomena in certain rare-earth ion doped materials have been implemented in our laboratory. The importance of these studies in fibers will be discussed. Infrared quantum counter studies in Eu, Tb, Ho, Er, and Pr doped fibers are proposed for future work.
