WebA flying focus triggers an ionization front that upshifts an ultrafast pulse from the optical to the extreme ultraviolet (XUV) E28544 • The theory of photon acceleration predicts impressive frequency upshifts but experiments are ultimately limited by two effects • Use of the flying focus effectively eliminates both of these effects WebSep 20, 2024 · A schematic demonstrating photon acceleration in the ionization front of a flying focus. A negatively chirped drive pulse propagating at its group velocity v d < 0 forms a focus that counterpropagates at the velocity v f = c, triggering an ionization front …

Web6.2 Flying Mirrors In Sect.4.1 we have mentioned that the laser wake wave in a plasma has phase velocity υp close to c and, moreover, the phase fronts of the density perturbation have a parabolic shape. Since a parabola should focus perfectly incoming radiation, the nonlinear wake wave is inspiring as a moving mirror or a flying mirror, quoting ctc mirys marcin
