Liquid Jet with Blue Laser
This image captures the intersection of engineering, physics and chemistry in the realm of optical-pump THz-probe spectroscopy. A blue laser momentarily renders the liquid jet impervious to THz radiation, creating the surreal image submitted here as well as the fastest triggerable electrical switch known to date (APL Photon., doi: 10.1063/5.0130236).
