    • Applications of digital holograms for the selection and detection of transverse laser modes. 

      Ngcobo, Sandile. (2014)
      The transverse mode of generally available commercial lasers in most instances is not suitable for desired applications. Shaping the laser beam either extra-cavity, that is outside the laser resonator, or intra-cavity, ...

    • Digital control of light. 

      Majola, Nombuso. (2019)
      The objective of this research was to describe innovative ways in which digital holography can be applied in controlling laser light. The ability to control and manipulate a laser beam has become an extremely desirable ...

    • Novel laser beams for optical trapping and tweezing. 

      Ismail, Yaseera. (2011)
      Optical trapping and tweezing has been around for the last 30 years and since found its place in the fields of physics and biology. Over the years this technique has advanced exceedingly and is a unique tool to carry out ...

    • Refractive effects in phase objects and associated phenomena. 

      Buccellato, Ricardo. (1994)
      The effect of the refraction of a laser beam propagating through three different phase objects, i.e. a laser produced plasma and two different gas media, is investigated in this thesis. It is shown that these effects ...
