  • von Bergmann, HM; Forbes, A; Roberts, T; Botha, LR (International Society for Optical Engineering, 2008-08)
    Results are presented on the influence of acoustic waves on the performance of high-repetition-rate TEA CO2 lasers. It is shown that acoustic waves generated inside the laser cavity lead to nonuniform discharges, resulting ...
  • Singh, A; Sharma, Ameeth; Roberts, T; Khutlang, R; Ramokolo, R; Marome, N; Webb, L; Botha, N; Karsten, A; Strauss, H (CSIR, 2015-10)
    This poster Celebrating the Year of Light….. from medicine to security with Optical Coherence Tomography was presented at the CSIR’s 5th Conference, 8-9 October 2015.
  • Du Plessis, A; Strydom, CA; Uys, H; Botha, L; Roberts, T; Dlamini, TH (CSIR, 2010-09)
    Femtosecond laser control of chemical reactions is made possible through the use of pulse-shaping techniques coupled to a learning algorithm feedback loop – teaching the laser pulse to control the chemical reaction. This ...

  • Von Bergmann, H; Forbes, A; Roberts, T; Botha, L (The International Society for Optical Engineering, 2007)
    In this paper the author’s present results on the influence of acoustic waves on the output laser beam from high repetition rate TEA CO2 lasers. The authors show that acoustic waves generated inside the cavity lead to ...
  • Molukanele, P; Du Plessis, A; Roberts, T; Botha, L; Khati, M; Campos, W (2011-09)
    Potential for the selective deactivation of viruses while leaving the sensitive material such as the host cell unharmed was studied using a femtosecond laser system, and preliminary results are reported.

  • Molukanele, P; Du Plessis, A; Roberts, T; Botha, L; Khati, M; Campos, W; Rotherham, L (CSIR, 2010-09-01)
    Viruses can be described as acellular organisms whose genome consists of nucleic acid that replicate inside living cells (host cells) using their cellular synthetic machinery, and cause the synthesis of specialised elements ...
  • Roro, Kittessa T; Tile, N; Yalisi, B; De Gama, M; Wittes, T; Roberts, T; Forbes, A (2011-05)
    A sol-gel technique has been established at a laboratory scale for low cost production of high efficient selective solar absorbers comprising a composite material of nano-structured carbon in a nickel oxide matrix. In order ...
