Lasers have become indispensable to modern life since they were invented more than fifty years ago. The ability to generate and amplify light waves into a coherent, monochromatic and well-focused beam...
Discrete symmetries of low-dimensional Dirac models: A selective review with a focus on condensed-matter realisations
relativistic quantum physics reduced dimensionality Dirac Hamiltonians quasi-relativity in solids
2012/6/2
The most fundamental characteristics of a physical system can often be deduced from its behaviour under discrete symmetry transformations such as time reversal, parity and chirality. Here we review ba...
Construction and Experimental Study of a 2.5kJ, Simply Configured, Mather Type Plasma focus device
Plasma focus Pinch Focusing time discharge current
2010/6/30
In this work, a 2.5kJ plasma focus device (named as SBUPF1) has been constructed on the basis of a simple configuration. The most important characteristics of this configuration is relative simplicity...
A lumped parameter model of free expanding Plasma Focus
Plasma Focus pinch plasma open-cathode modeling
2009/12/31
In this paper, a model of Plasma Focus without surrounding cathode containing the radial expansion of the current sheath is presented. This configuration has been increasingly used in recent miniature...
Multiple Patterning of Laser Focus Spot Using a Segmented Kinoform Phase Plate
Kinoform phase plate Computer-generated hologram Laser fusion
2009/6/8
An important technique required in the application of laser systems to fusion is the ability to generate high energy to satisfy the conditions for self-ignition and to improve the uniformity of laser ...
Tight focus ing of elliptic ally polarized vortex beams
Tight focusing elliptic ally polarized vortex beams
2008/10/30
We study the focusing properties of elliptically polarized vortex beams. Based on vectorial Debye theory,some numerical calculations are given to illustrate the intensity and phase distribution proper...
Focus shaping of cylindrically polarized vortex beams by a high numerical-aperture lens
Wave optics Beam shaping Polarization
2007/8/25
The focus-shaping technique of a cylindrically polarized vortex beam by a high numerical-aperture lens is reported. Such a polarized vortex beam is decomposed into radial and azimuthal polarization. I...
