  3. Broadly tuneable crystalline Raman lasers

    Casula, RiccardoUniversity of Strathclyde2020

    … of a continuous-wave third-Stokes crystalline Raman laser. This was achieved via intracavity Raman conversion of a vertical external cavity surface emitting laser (VECSEL), also known as a semiconductor disk laser (SDL). The VECSEL-pumped Raman laser achieved Watt-level output and broad …

  4. Investigating physical properties of novel carbon-based materials

    Demir, Nasser Soliman, 1982-Massachusetts Institute of Technology2004

    … graphitic foams. The experimental technique of Raman laser spectroscopy yields structural information about all of these materials that we are investigating, including how the covalent bonds between the carbon atoms in the base of the material change in the presence of metal doping (in the case …

  6. Dynamics in a Fermi lattice gas

    Xu, WenchaoUniversity of Illinois at Urbana-Champaign2018

    … a Fermi-Hubbard optical lattice model by applied Raman laser fields. This correlated tunneling involves spin-flips and the generation of doublons, which have been observed experimentally. We also confirmed that the amplitude of correlated tunneling is suppressed when neighboring lattice sites are …

  9. Thermal and spectral effects in intracavity Raman lasers

    Bonner, Gerald MichaelUniversity of Strathclyde2013

    Stimulated Raman scattering is a convenient way to extend the spectral coverage of well-established solid-state laser sources. In an intracavity Raman laser, a Raman crystal is placed inside the cavity of the fundamental laser, and the output frequency is red-shifted by an amount corresponding to a …

  10. Magnetic field reversal effect in inter-Landau level absorption and simulated spin-flip Raman scattering in n-type InSb

    Favrot, Gervais F. (Gervais Freret), 1948-Massachusetts Institute of Technology1998

    … Experiments were carried out on the spin-flip Raman laser to examine crystal anisotropy. An important feature of this research is the prediction and observation of a striking magnetic field reversal effect in the inter-Landau level magnetoabsorption in n-InSb. The magnitude of the absorption …

  11. High-power cladding-pumped Raman and erbium-ytterbium doped fibre sources

    Codemard, Christophe AndréUniversity of Southampton2007

    Raman fibres and rare-earth doped silica fibres have been investigated for many years as gain media for the amplification of optical signals in telecommunications thanks to their broad gain bandwidth. They are now widely used for that application. It is only recently that power scaling of fibre …
