Generating shaped femtosecond pulses in the far infrared using a spatial light modulator and difference frequency generation

Author: Botha, N ; Botha, L ; Du Plessis, A ; Schwoerer, H Date: 31 Aug 2010 Femtosecond 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
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
Pulse shaping and characterization with a 4f system

Author: Botha, N ; Botha, L ; Du Plessis, A ; Uys, H ; Schoewer, H Date: Oct 2010 The 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

White light wavefront control with a spatial light modulator

Author: Spangenberg, D-M ; Dudley, Angela L ; Neethling, PH ; Rohwer, EG ; Forbes, A Date: 2014 Spatial light modulators are ubiquitous tools for wavefront control and laser beam shaping but have traditionally been used with monochromatic sources due to the inherent wavelength dependence of the calibration process and subsequent phase ...
