Poynting vector and orbital angular momentum density of superpositions of Bessel beamsIgor A Litvin
CSIR National Laser Centre, Pretoria, South Africa
Opt Express 19:16760-71. 2011..Knowledge of the OAM distribution has relevance in optical trapping and tweezing, and quantum information processing...
Intra-cavity flat-top beam generationIgor A Litvin
CSIR National Laser Centre, PO Box 395, Pretoria 0001, South Africa
Opt Express 17:15891-903. 2009..We show that both have good convergence properties, and result in the desired stable mode...
Intra-cavity generation of Bessel-like beams with longitudinally dependent cone anglesIgor A Litvin
CSIR National Laser Centre, PO Box 395, Pretoria 0001, South Africa
Opt Express 18:4701-8. 2010..In both cases we show that the LDBLB is the lowest loss fundamental mode of the cavity, and show theoretically the extended propagation distance expected from such beams...
Azimuthal decomposition with digital hologramsIgor A Litvin
CSIR National Laser Centre, Pretoria, South Africa
Opt Express 20:10996-1004. 2012..From the measured decomposition we show reconstruction of the amplitude, phase and orbital angular momentum density of the field with a high degree of accuracy...
