Intra–cavity laser beam shaping
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: There are many applications where a Gaussian laser beam is not ideal, for example, in areas such as medicine, data storage, science, manufacturing and so on, and yet in the vast majority of laser systems ...
Flattened Gaussian beam for laser paint removal
(Stellenbosch : Stellenbosch University, 2011-03)
ENGLISH ABSTRACT: Lasers are commonly used in the industry for various applications such as laser cutting, laser drilling, lithography, medical applications, surface cleaning and a myriad of other applications. In any ...
Spectral characteristics of stimulated Raman scattered radiation in a waveguide
(Stellenbosch : Stellenbosch University, 1992-01)
ENGLISH ABSTRACT: The spectral characteristics of stimulated Raman scattered radiation in a waveguide was investigated using a laser as source of pump radiation. The pump laser is focused into the waveguide to obtain a ...
Correlations between the standard and alternative definitions of the beam quality factor
(Stellenbosch : University of Stellenbosch, 2005-04)
ENGLISH ABSTRACT: The beam quality factor (M2) of a laser is important because it describes both the quality of a laser beam as well as its propagation. Particular applications require that the beam radii (from which ...
A characterization of beam shaping devices and a tunable Raman laser
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: The efficient manipulation of various nonlinear optical processes frequently requires the shaping of the laser beams used for these processes. Three beam shaping techniques were investigated in this ...
