  • The powders of Mg(Al1-xEux)2O4 have been synthesized by sol-gel method. Optical properties of the material were investigated. The nature of lines in luminescence spectra is related to the electron transitions of Eu3+ ions corresponding to different sites in the lattice. The influence of Eu concentration on optical spectra was studied.

  • During the years surrounding the new millennium, the field of vibrational optical activity (VOA), comprised principally of vibrational circular dichroism (VCD) and vibrational Raman optical activity (ROA), underwent a transition from a specialized area of research that had been practiced by a handful of pioneers into an important newfield of spectroscopy practiced by an increasing number of scientists worldwide. This transition was made possible by the development of commercial instrumentation and software for the routine measurement and quantum chemical calculation ofVOA.

  • This chapter provides the basis for the discussion in the following chapters by summarizing the fundamental concepts and the quantum theory concerning the interaction between electrons and photons in a form that is convenient for theoretical analysis of semiconductor lasers [1–9]. First, quantization of electromagnetic fields of optical waves is outlined, and the concept of a photon is clarified. Quantum theory expressions for coherent states are also given. Then the quantum theory of electron–photon interactions and the general characteristics of optical transitions are explained. ...

  • Excimer lasers are pulsed gas lasers that intrinsically offer efficient and powerful broadband emission at several spectral regions throughout the ultraviolet. The spectral widths are typically 2 nm. An exception to this categorization is the XeF laser urith its broadly tunable C+A transition (approximately 50 nm) in the visible. The broad tunability results from the steeply repulsive A state.

  • Hydrogenated amorphous silicon, a new form of a common element, is a semiconductor that has come of age. Its scientific attractions include a continuously adjustable band gap, a usable camer lifetime and diffusion length, efficient optical transitions, and the capability of employing either nor p-type dopants. Furthermore, it can be fabricated very easily as a thin film by a technology that not only inherently escapes the expenst: of crystal perfection but also requires significantly smaller amounts of raw materials....

  • ADC’s innovative line of indoor/outdoor loose tube cables are designed to meet all the rigors of the outside plant environment and have the necessary fire ratings to be installed inside the building. These cables eliminate the messy gel filler of traditional loose tube style cables with super absorbent polymers. The installer can place the cable anywhere in the network, bypassing the transition points required in most installations. Cables are available with fiber counts from 2 to 144.

  • There is hardly any book that aims at solving problems typically encountered in the laser field, and this book intends to fill the void. Following some initial exercises related to general aspects in laser physics (Chapt. I), the subsequent problems are organized along the following topics: (i) Interaction of radiation with matter either made of atoms or ions, weakly interacting with surrounding species, or made of more complicated elements such as molecules or semiconductors (Chapters 2 and 3). (ii) Wave propagation in optical media and optical resonators (Chapters 4 and 5)....

  • The prototype of the barbute may be seen in a basinet from Chalcis, dating from 4I 0 to I440, portrayed in the drawings. It retains vervelles along the edges for attaching a camail. Minus the camail, and with a rounded bowl to conform with the contour of the head, this helmet would qualify as a barbute. In fact, the transition from basinet to barbute is largely a change in propor- tion. Some basinets were so tall that they rested on ...

  • Cathodoluminescence (CL) is a non-destructive technique to characterize optical and electronic properties of nanostructures in many kinds of materials. Major subject is to investigate basic parameters in semiconductors, impurities in oxides and phase determination of minerals. CL is similar to photoluminescence (PL) technique, but the excitation by high energy electrons can produce all the transition to the higher energy excitation states and induce light emission in the wide energy range concerned with versatile types of electronic transitions in materials....
