Picosecond Holographic Grating Generation of Ultrasonic Waves
The picosecond holographic grating generation and detection of ultrasonic waves are described. Two mechanisms, a heating mechanism and a stimulated Brillouin scattering mechanism, are described. These permit the generation of tunable ultrasonic waves in the MHz to GHz range. It is demonstrated that the two mechanisms can be distinguished by the distinct time dependences of the diffraction of a ...
متن کاملPicosecond Emission Spectroscopy
A picosecond emission apparatus utilizing a mode locked Nat3 /phosphate glass laser and a streak camera -optical -multichannelanalyzer detection system is described, and some general classes of experiments in this research area are discussed. Special emphasis is placed on nonexponential decays. A new type of diffusion controlled chemical reaction based on rotational diffusion is proposed for st...
متن کاملUltra-low frequency Stokes and anti-Stokes Raman spectroscopy at 785nm with volume holographic grating filters
We report the first results of ultra-low frequency Stokes and anti-Stokes Raman spectra at 785nm showing clearly resolved frequency shifts down to 10cm -1 from the excitation line, using commercially available ultra-narrow band notch and ASE suppression filters, and a single stage spectrometer. Near infra-red (NIR) wavelengths are of particular interest for Raman spectroscopy due to the reduced...
متن کاملPolarization of holographic grating diffraction. II. Experiment.
The transmittance, ellipsometric parameters, and depolarization of transmission, diffraction, and reflection of two volume holographic gratings (VHGs) are measured at a wavelength of 632.8 nm. The measured data are in good agreement with the theoretical simulated results, which demonstrated the correlation between the diffraction strength and the polarization properties of a VHG. Vector electro...
متن کاملPicosecond polarization-selective transient grating experiments in sodium-seeded flames
Polarization-selective transient grating experiments have been used to study the subnanosecond time scale dynamics of several sodium-seeded, premixed flames. Intensity gratings (in which both excitation beams are of the same polarization) were used to determine excited-state quenching collision rates, while polarization gratings (in which the excitation beams are cross polarized) were used to m...
