Abstract
In Part 1 of this book, external electromagnetic field induced structures in glasses and other materials and promising applications in various fields such as integrated optics and optical communications were introduced. From the viewpoint of material design, it is important to clarify the formation mechanism of the induced structures. In this chapter a novel method for the direct observation of excited-state absorption of rare-earth ions is introduced [203] . The valence state and chemical bond state of rare-earth ions in glasses showing room-temperature spectral hole burning and photostimulated luminescence were examined by using X-ray absorption fine structures (XAFS) [205] . Microscopic Raman scattering spectroscopy was used to study the focused femtosecond infrared laser induced structural change in SiO2 glass in Sect. 4.4.
