Light Scattering with Laser Sources

  title={Light Scattering with Laser Sources},
  author={Sergio P. S. Porto},
When light passes through matter weak random scattered radiation appears. In the early 16th Century, Leonardo da Vinci prophetically suggested scattering by particles of air as the explanation for the blueness of the sky. This idea was pursued by many scientists including Newton and Tyndall who tried with only limited success to identify the particles responsible for the scattering. Lord Rayleigh[1] following a suggestion by Maxwell, finally proved that the air molecules themselves were… 
Temperature Diagnostics for Laser Writing
Infrared (IR), Raman, and luminescence measurements are discussed with respect to their application as temperature probe during laser writing. IR measurements on the high energy side of the Planck
Raman Spectroscopy of High Pressure Phases of Solids
This report concerns one role of Raman spectroscopy for observing the behavior of solids under high pressures—that is, Raman spectroscopy is an experimental technique for characterizing in situ
Time‐resolved Raman spectra of photoexcited semiconductor plasma
A theoretical study of time-resolved Raman scattering by a highly photoexcited semiconductor plasma is developed. The scattering cross-section is calculated using the Zubarev non-equilibrium ensemble
Characterization of Materials by Raman Scattering
The paper reports on the use of phonon spectra obtained with the Raman spectroscopy for characterization of different materials. The Raman scattering spectra obtained for zinc selenide crystals,

Labor-Demonstration eines Brillouin-LIDARs zur Messung des Temperaturprofils in Wasser
Die Ozeane bedecken uber 70% der Erdoberflache. Aufgrund ihrer Ausdehnung und vielfaltigen Kopplung an die Atmosphare agieren sie als Motor des globalen Klimas. Der Warmegehalt der Ozeane stellt
Raman Scattering Spectroscopy and Analyses of III-V Nitride-Based Materials
This paper reviews Raman studies of GaN, A1N, InN, and the alloy systems GaxAl1–xN and InxGa1–xN. The review focuses on the applications of Raman spectroscopy to material characterizations and phonon


A New Type of Secondary Radiation
IF we assume that the X-ray scattering of the ‘unmodified’ type observed by Prof. Compton corresponds to the normal or average state of the atoms and molecules, while the ‘modified’ scattering of
Acoustic beam probing using optical techniques
In Section I it is demonstrated that the amplitude of the light deflected or scattered by an advancing sinusoidal acoustic wave, as a function of the angle between the direction of light propagation
Change of Wave-length of Light due to Elastic Heat Waves at Scattering in Liquids.
SOON after the discovery of the Raman effect, I attempted to find out whether in light scattered in various organic liquids the Raman lines, due to frequencies of the rotation spectrum, are present.
High-Resolution Raman Spectroscopy of Gases with cw-Laser Excitation*
Several techniques of exciting Raman spectra of low-pressure gases and vapors with cw laser radiation are described. Both the He–Ne laser with output at 6328 a and the Ar+ ion laser with output at
The Raman effect in crystals
A review is given of progress in the theoretical and experimental study of the Raman effect in crystals during the past ten years. Attention is given to the theory of those properties of
