Maximum-information photoelectron metrology

Maximum-information photoelectron metrology

Two new articles, on quantum metrology via polarization-shaped pulses (mostly theory) and maximum-information photoelectron metrology via tomographic measurements (mostly experiment), have just been published in PRA.

Information content of polarization-shaped pulses

Information content of polarization-shaped pulses

Playing around with visualization of the information content of polarization-shaped pulses, which represent a way to coherently sample (over the pulse duration) a range of points in polarization space.  Here’s a plot showing the coherent paths followed for a range of different pulses, generated by putting a step function on the spectral phase of a broadband (~60fs) pulse, with the instantaneous pulse polarization expressed as Stokes vectors and projected onto a Poincare Sphere.

Update 4th May – the manuscript (a version of) this figure appears in is now on the arxiv.
