Development of a high power femtosecond laser

Author: Neethling, PH ; Rohwer, EG ; Schwoerer, H ; Botha, L Date: Oct 2010 The Laser Research Institute and the CSIR National Laser Centre are developing a high power femtosecond laser system in a joint project with a phased approach. The laser system consists of an fs oscillator and a regenerative amplifier. An ... Read more
Femtosecond laser induced and controlled chemical reaction of carbon monoxide and hydrogen

Author: Du Plessis, A ; Strydom, CA ; Uys, H ; Hendriks, A ; Botha, GN ; Botha, LR Date: Jul 2011 Results from experiments aimed at bimolecular chemical reaction control of CO and H2 at room temperature and pressure, without any catalyst, using shaped femtosecond laser pulses are presented. A stable reaction product (CO2) was measured ... Read more
Femtosecond pump probe spectroscopy for the study of energy transfer of light-harvesting complexes from extractions of spinach leaves

Author: Ombinda-Lemboumba, Saturnin ; Du Plessis, A ; Sparrow, RW ; Molukanele, P ; Botha, LR ; Rohwer, EG ; Steenkamp, CM ; Van Rensburg, L Date: Sep 2009 Measurements of ultrafast transient processes, of temporal durations in the picosecond and femtosecond regime, are made possible by femtosecond pump probe transient absorption spectroscopy. Such an ultrafast pump probe transient absorption ... Read more
In-vitro photo-translocation of antiretroviral drug delivery into TZMbl cells

Author: Malabi, Rudzani ; Manoto, Sello L ; Ombinda-Lemboumba, Saturnin ; Maaza, M ; Mthunzi-Kufa, Patience Date: Jan 2017 The current human immunodeficiency virus (HIV) treatment regime possesses the ability to diminish the viral capacity to unnoticeable levels; however complete eradication of the virus cannot be achieved while latent HIV-1 reservoirs go ...

Influence of amplification on pulse shaping for coherent control applications

Author: Du Plessis, A ; Botha, GN ; Botha, LR Date: Jul 2011 Results from experiments aimed at bimolecular chemical reaction control of CO and H2 at room temperature and pressure, without any catalyst, using shaped femtosecond laser pulses are presented. A stable reaction product (CO2) was measured ... Read more
Photo-transfection of mouse embryonic stem cells with plasmid DNA using femtosecond laser pulses

Author: Thobakgale, Setumo L Date: Jan 2017 This presentation is about the photo-transfection of mouse embryonic stem cells with plasmid DNA using femtosecond laser pulses. It outlines the background on embryonic stem cells (ES) and phototransfection. Read more

Pros and cons of characterising an optical translocation setup

Author: Maphanga, Charles P ; Malabi, Rudzani ; Ombinda-Lemboumba, Saturnin ; Maaza, M ; Mthunzi-Kufa, Patience Date: Feb 2017 The delivery of genetic material and drugs into mammalian cells using femtosecond (fs) laser pulses is escalating rapidly. This novel light based technique achieved through a precise focusing of a laser beam on the plasma membrane is called ... Read more
