We present the results of an experimental and numerical investigation intotemporally non-local coherent interactions between ultrashort pulses, mediatedby Raman coherence, in gas-filled kagom\'{e}-style hollow-core photonic crystalfiber. A pump pulse first set up the Raman coherence, creating a refractiveindex grating in the gas that travels at the group velocity of the pump pulse.Varying the arrival time of a second probe pulse allows high degree of controlover its evolution as it propagates along the fiber, in particular solitonself-compression and dispersive wave (DW) emission. In the experimentsreported, a DW is emitted at ~300 nm, with a central frequency that oscillateswith the pump-probe delay. The results demonstrate that strong Raman coherencecreated in broadband guiding gas-filled kagom\'e-PCF can be used to control thedynamics of ultrashort probe pulses, even in difficult-to-access spectralregions such as the deep and vacuum ultraviolet.
