X-ray/Optical Wave Mixing Experiment Diagram (image) DOE/Lawrence Berkeley National Laboratory Caption Pulses of 8,000-electron-volt x-rays from the LCLS are synchronized with 1.55 electron-volt pulses from an optical laser, so that both strike the diamond sample at the same time and mix to form upconverted pulses of 8,001.55 electron volts. The detector first sees the diffracted x‑ray pulse, and then, after the sample is gently "rocked," the slightly more energetic mixed pulse. The optical pulse exerts localized force on the chemical bonds among the carbon atoms. Credit Thornton Glover et al.
