New Success for Konstanz Physicists in Studying the Quantum Vacuum (2 of 3) (IMAGE)
Caption
Detailed view of the central part of the experiment on subcycle quantum electrodynamics. The gallium selenide emitter crystal is seen in the bright region to the right. Here, an ultrashort laser pulse induces a local change in the velocity of light which leads to squeezing of the quantum vacuum. The nonclassical states of light propagate through the filters in the center and end up at the silver gallium sulfide detection crystal which is highlighted in the left section. The deviations from the vacuum noise are sampled there with femtosecond time resolution.
