But nor is it a space station. While it might bear some resemblance to a certain location from a famous film franchise, today’s Image of the Week entry is actually a visual representation of the properties of a laser pulse. The image below is a photoelectron interferogram of a polarization-shaped laser pulse, shown in a representation called an iso-sphere. The features on the sphere and the 2D projections around its sides show how the laser pulse propagates in terms of various parameters.
The image comes from a paper by researchers working in Canada and Germany, in which they study the coherent control of electron wavepackets using laser pulses. To find out more about their research and to see more images like the one above, you can read P Hockett et al 2015 J. Phys. B: At. Mol. Opt. Phys. 48 214004
