“…Much smaller portions of the scattered light are observed at various wavelengths shifted up or down with respect to that of the incident light. This is the Raman scattering, first discovered by Raman and Krishnan [16]. These shifts occur as atoms are excited by the incident photon from its ground state and then relaxed to different vibrational energy states.…”

International audienceRaman spectroscopy has in recent years been used by several research groups to study the stresses that develop in thermally grown oxide layers, particularly Cr(2)O(3), at elevated temperatures between 700 and 900 A degrees C. This paper presents an overview of the Raman technique and describes quantitatively the factors that, in addition to stress, affect the Raman peak shifts, including temperature, non-stoichiometry, impurities, stresses and instrumental calibration. It also summarizes and reviews published work in this area and in doing so, discusses the pros and cons of this technique for oxidation stress measurements

“…РАССЕЯНИЕ В КВАРЦЕ Мы имели два кристалла кварца. Их размеры были 25 X 30 X 30 и 20 X 40 X 40 мм 3 . В одном из этих кристаллов при облучении ультра-фиолетовым светом наблюдалась заметная фосфоресценция, другой был от нее свободен.…”

“…Raman spectroscopy, being a vibrational spectroscopy, provides valuable characteristic information about molecular species and their chemical bonds [2][3][4]. When compared with other molecular-specific imaging techniques (e.g., fluorescence, chemiluminescence or radioactivity microscopies), Raman spectroscopy provides a label-free contrast mechanism intrinsically induced by the molecules contained in the sample.…”

Stimulated Raman scattering (SRS) microscopy is a powerful tool for chemically-sensitive non-invasive optical imaging. However, the short-pulse laser sources, which are currently being employed for this imaging technique, are still expensive and require substantial maintenance to provide temporal and spectral overlap. SRS imaging, which utilizes cw laser sources, has a major advantage over pulsed lasers, as it eliminates the possibility of cell damage due to exposure to high-intensity light radiation, while substantially reducing the cost and complexity of the set-up and keeping a subcellular spatial resolution. As a proof-of-principle, we demonstrate microscopic imaging of dimethyl sulfoxide using two independent, commonly used and inexpensive lasers: a diode-pumped, intracavity doubled 532 nm laser and a He-Ne laser operating at 633 nm. In our proof-of-principle experience, dimethyl sulfoxide acts as a contrast agent providing Raman scattering signal. The 532 nm and 633 nm lasers act as excitation and probe sources, respectively [1].
