  • Time domain pulse shaping using a genetic algorithm 

    Mori, Andrew (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: Through the use of complex Laser Pulse Shaping, numerous fundamental laser induced processes may be controlled as well as studied. This work serves as an introduction into Laser Pulse Shaping, with the ...

  • Thermo-optical effects in high-power end-pumped vanadate lasers 

    Strauss, Hencharl Johan (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The output power of end-pumped lasers is mainly limited by thermal effects in the bulk crystal gain material. The thermal effects either fracture the crystal or cause degradation in the laser beam quality ...

  • Short-pulse generation in a diode-end-pumped solid-state laser 

    Ngcobo, Sandile (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: This thesis consists of two parts; the first part is a discussion on the detailed history of the development of different types of modelocked lasers, especially the neodymium-doped lasers. The second ...

  • Monte Carlo simulation of direction sensitive antineutrino detection 

    Blanckenberg, J. P (Jacobus Petrus) (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: Neutrino and antineutrino detection is a fairly new eld of experimental physics, mostly due to the small interaction cross section of these particles. Most of the detectors in use today are huge ...

  • Intra–cavity laser beam shaping 

    Litvin, Igor A. (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: There are many applications where a Gaussian laser beam is not ideal, for example, in areas such as medicine, data storage, science, manufacturing and so on, and yet in the vast majority of laser systems ...

  • International astronomer Phil Charles meets the ire of the National Research Foundation 

    Bohm, Lothar (Academy of Science of South Africa (ASSAf), 2010-03)
    Recent weeks have seen an embarrassing display of heavy-handed National Research Foundation (NRF) management in connection with the Square Kilometer Array (SKA) project – a new $2 billion radio astronomy facility to be ...

  • Fuel management study for a pebble bed modular reactor core 

    Movalo, Raisibe Shirley (Stellenbosch : Stellenbosch University, 2010-03)
    ENGLISH ABSTRACT: This dissertation reports on the impact of a set of selected nuclear fuel management parameters on reactor operations of the PBMR core. This is achieved by performing an assessment of the impact of ...

  • A feasibility study of the (3He,8He) reaction with the K600 magnetic spectrometer 

    Swartz, Jacobus Andreas (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: Highly exotic nuclei can be studied in rare reactions using stable beams, with macroscopic intensities, and thick targets. Exotic nuclei are interesting for a number of reasons e.g. for testing nuclear ...

  • Analyzing power and cross section distributions of the 12C (p,pα)8Be cluster knockout reaction at an incident energy of 100 MeV 

    Mabiala, Justin (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The (p, pα) reaction on 12C was investigated experimentally using polarized incident protons of 100 MeV. Coincident data, which were obtained at ten quasifree angle pairs for proton angles ranging from ...
