The crystallographic, optical, and spectroscopic properties of Neodymium(3+):Yttrium scandium aluminum garnet are reported from which an assessment can be made regarding the material's potential as a laser. Individual Stark levels for many of the (2S+1)Lj manifolds of Nd(3+) (4f3) in the crystal have been identified from emission and absorption data up to 17,600/cm at 14K. The observed crystal-field splitting and the measured cross sections (intensities) associated with manifold-to-manifold transitions are compared with calculated splittings and calculated intensities. Branching ratios and diode- array-pumped laser slope efficiencies are also reported. We conclude that Nd(3+) :YSAG has potential as a diode-pumped 1-micrometer laser material. (JG).

Photoacoustic and Photothermal Spectroscopy: Principles and Applications introduces the basic principles, instrumentation and major developments in the many applications of Photoacoustic and Photothermal Spectroscopy over the last three decades. The book explains the processes of sound generation by periodic optical excitation and ultrasonic generation by pulsed laser excitation and describes the workings of photoacoustic cells equipped with microphones and piezoelectric transducers. Photoacoustic imaging (PAI) is one of the fastest-growing imaging modalities of recent times. It combines the advantages of ultrasound and optical imaging techniques. These non-invasive and non-destructive techniques offer many benefits to users by enabling spectroscopy of opaque and inhomogeneous materials, (solid, liquid, powder, gel, gases) without any sample preparation, and more. Written in a non-mathematical, simple-to-read manner Presents recent developments in the field, along with the scope of future progress, including up-to-date references Includes detailed illustrations, such as equipment layout, spectra, experimental setups, tables, photographs, and more

By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.
