Enhanced distributed hybrid sensor based on Brillouin and Raman scattering combining Fabry-Perot lasers and optical pulse coding
Fiber optics sensors Scattering Brillouin Scattering Raman
2015/6/8
Pulse coding techniques are proposed in combination with the use of Fabry-Perot lasers for simultaneous strain and temperature sensing based on hybrid spontaneous Raman-Brillouin scattering.Combinatio...
Inter-Wavelength Transfer of Digital Lightpath Labels Induced by Stimulated Raman Scattering
Fiber optics links and subsystems All-optical networks Fiber optics communications Nonlinear optics fibers
2015/6/4
WDM systems using digital lightpath labels can experience modulation transfer among wavelengths due to stimulated Raman scattering (SRS), creating label replicas. We present pump-probe measurements of...
Laser Pulse Compression and Amplification by Stimulated Backward Raman Scattering of Ba(NO3)2 and CaCO3 Crystals
Laser pulse compression Stimulated backward Raman scattering Short pulse laser
2009/6/15
Pulse compressor and amplifier using stimulated backward Raman scattering (SRS) of barium nitrate and calcite crystals are studied experimentally. 15 times of compression and more than 50 % SRS reflec...
Development of Coherent Anti-Stokes Raman Scattering Microscopy
Nonlinear spectroscopy Ultra-fast laser Raman spectroscopy microscopy
2009/6/12
New multiphoton microscopy using CARS (Coherent Anti-Stokes Raman Scattering) spectroscopy is described. In CARS microscopy, the image of molecular vibration that is sensitive to the molecular spices ...
Experimental investigation of Brillouin and Raman scattering in a Ge 15 Sb 20 S 65 microstructured chalcogenide fiber
Brillouin Raman scattering microstructured chalcogenide fiber
2015/8/3
We investigate the Brillouin and Raman properties of a Ge 15 Sb 20 S 65 chalcogenide microstructured fiber around 1550nm. We have found Brillouin and Raman gain coefficients 100 and 180 larger than fu...
