  • Development of VUV tunable laser spectroscopy techniques for characterizing calcium fluoride 

    Matindi, Tresor (Stellenbosch : Stellenbosch University, 2014-12)
    ENGLISH ABSTRACT: The large band gap (approximately 11.5-12.1 eV) and high transmission of calcium fluoride (CaF2) crystal in the ultraviolet (UV) and vacuum ultraviolet (VUV) region makes it an important material for ...

  • Diagnostics in VUV laser spectroscopy 

    Huang, Ping (Stellenbosch : University of Stellenbosch, 2005-03)
    A tunable vacuum ultra-violet (VUV) laser source was recently developed for VUV spectroscopy using state selective excitation and total fluorescence detection. The VUV laser source makes use of a four-wave mixing process ...

  • Influence of gas discharge parameters on emissions from a dielectric barrier discharge excited argon excimer lamp 

    Baricholo, Peter; Hlatywayo, Dumisani J.; Von Bergmann, Hubertus M.; Stehmann, Timo; Rohwer, Erick; Collier, Mike (ASSAF -- Academy of Science of South Africa, 2011-11)
    A dielectric barrier discharge excited neutral argon (Ar I) excimer lamp has been developed and characterised. The aim of this study was to develop an excimer lamp operating at atmospheric pressure that can replace mercury ...

  • Laser spectroscopy of the Fourth Positive System of carbon monoxide isotopomers 

    Du Plessis, Anton (Stellenbosch : University of Stellenbosch, 2006-03)
    Carbon monoxide (CO) is a diatomic molecule of particular interest in astrophysics, due to its high abundance in interstellar space. The Fourth Positive System A1Π−X1Σ+ of CO is an important feature in the vacuum ultraviolet ...

  • Vacuum ultraviolet laser spectroscopy of CO molecules in a supersonic jet 

    Steinmann, C. M. (Christine Margarete) (Stellenbosch : Stellenbosch University, 2003-12)
    ENGLISH ABSTRACT: A tunable narrow-bandwidth laser source combined with a supersonic gas jet as sample is wellsuited for obtaining high-resolution spectra of cold isolated molecules and complexes. In the present study ...
