Refractive effects in phase objects and associated phenomena.
(1994)
The effect of the refraction of a laser beam propagating through three different
phase objects, i.e. a laser produced plasma and two different gas media,
is investigated in this thesis. It is shown that these effects ...
Progress with the colliding shock lens.
(2013)
The Colliding Shock Lens (CSL) exploits the interference of shock waves in a gas to
form a region in which high pressure, temperature and density change the refractive
index of the gas, making it possible to focus laser ...
Laser applications and refractive properties of non-homogeneous gas distributions.
(1995)

Applications of light scattering and refraction by atmospheric gases.
(2002)
LIDAR, an acronym for LIght Detection And Ranging, is a system used for studying
the scattering of laser light incident on a parcel of air. This thesis investigates the
atmosphere above the Durban region using two ...
Photothermal refraction and focusing.
(1997)
This thesis begins with an introduction to the interaction and refraction of light
in continuous media. It is shown how these properties can be exploited to achieve
focusing of parallel light rays in such a medium. Past ...
