Weak measurements of a large spin-dependent angular splitting of light beam on reflection at Brewster angle
Weak measurements light beam reflection Brewster angle Optics
2012/5/31
We reveal a large spin-dependent angular splitting of light beam on reflection at Brewster angle both theoretically and experimentally. A simple weak measurements system manifesting itself for the bui...
Study of tunable resonances in laser beam divergence and beam deflection
Tunable radiofrequency resonances noise of lasers beam-width fluctuation beam-deviation fluctuation
2012/5/29
New, fundamental resonant properties of laser resonators are theoretically predicted and experimentally demonstrated. These resonances occur either in the time dependence of the beam width and that of...

Active Negative Index Metamaterial Electron Beam Optics
2012/5/17
A novel active negative index metamaterial that derives its gain from an electron beam is intro- duced. The metamaterial consists of a stack of equidistant parallel metal plates perforated by a period...

2012/4/19
We describe how the notion of optical beam shifts (including the spatial and angular Goos-H\"anchen shift and Imbert-Federov shift) can be understood as a classical analogue of a quantum measurement o...

Abstract: We theoretically investigate the process of coupling cold atoms into the core of a hollow-core photonic-crystal optical fiber using a blue-detuned Laguerre-Gaussian beam. In contrast to the ...
Abstract: When a beam of light is reflected by a smooth surface its behavior deviates from geometrical optics predictions. Such deviations are quantified by the so-called spatial and angular Goos-Haen...
