Generation of high order modes

Author: Ngcobo, Sandile ; Ait-Ameur, K ; Forbes, A Date: Jul 2012 This work deals with the generation of symmetrical high order Laguerre Gaussian modes. These high order Laguerre-Gaussian beams are generated by forcing the laser using an annular binary Diffractive Optical Element whose geometry is in ... Read more
High Efficient LGp0 End Pumped Nd:YAG Laser

Author: Ngcobo, Sandile ; Forbes, A ; Ait-Ameur, K Date: Jul 2012 The transformation of a single mode TEM00 Gaussian beam by forcing the laser to operate into a symmetrical single mode higher order TEMp0 Laguerre Gaussian beam intensity distribution is very useful in improving and substantially increasing ...

Higher-order Bessel like beams with z-dependent cone angles

Author: Ismail, Y ; Barnes, G ; Mhlanga, T ; Belyi, V ; Forbes, A Date: Aug 2010 As in the case of zero-order Bessel beam being produced by illuminating an axicon with a Gaussian beam, higher-order Bessel beams are generated by substituting the Gaussian beam with a Laguerre Gaussian (LG) beam. These beams hold similar ... Read more
Superresolution beams

Author: Ngcobo, Sandile ; Ait-Ameur, K ; Forbes, A Date: Nov 2011 The transformation of a Gaussian beam (GB) into a symmetrical higher order TEMp0 Laguerre Gaussian beam (LGB) intensity distribution of which is further rectified and transformed into a Gaussian intensity distribution in the plane of a ...

Superresolution beams

Author: Ngcobo, Sandile ; Forbes, A ; Ait-Ameur, K ; Mhlanga, T Date: Jul 2012 The transformation of a Gaussian beam into a symmetrical TEMp0 Laguerre Gaussian beam (LGB) intensity distribution which has transverse superresolution properties is very useful in improving the spatial resolution of optical imaging microscopes ...
