Phys. Rev. Lett. 103, 152301 (2009) [4 pages]Yoctosecond Photon Pulses from Quark-Gluon Plasmas
See accompanying Physics Synopsis Present ultrafast laser optics is at the frontier between atto- and zeptosecond photon pulses, giving rise to unprecedented applications. We show that high-energetic photon pulses down to the yoctosecond time scale can be produced in heavy-ion collisions. We focus on photons produced during the initial phase of the expanding quark-gluon plasma. We study how the time evolution and properties of the plasma may influence the duration and shape of the photon pulse. Prospects for achieving double-peak structures suitable for pump-probe experiments at the yoctosecond time scale are discussed. © 2009 The American Physical Society URL:
