Author:Botha, N; Botha, L; Du Plessis, A; Schwoerer, HDate:31 Aug 2010Femtosecond pulse shaping can be done by different kinds of pulse shapers, such as liquid crystal spatial light modulators (LC SLM), acousto optic modulators (AOM) and deformable and movable mirrors. A few applications where pulse shaping is ...Read more
Author:Du Plessis, A; Botha, GN; Botha, LRDate:Jul 2011Results 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
Author:Botha, N; Botha, L; Du Plessis, A; Uys, H; Schoewer, HDate:Oct 2010The design of the pulse shaping setup as well as factors taken into account in choosing a specific setup will be discussed. We investigate the generation of simple shaped pulses to test our pulse shaper setup. Difference frequency mixing is ...Read more
