(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...
Random fluctuations in the intensity and energy of X-ray lasers, which generally limit performance, have been harnessed for high-resolution spectroscopy. Li and colleagues use an XFEL to produce a ...
