Next-generation X-ray sources have allowed new opportunities for ultrafast imaging, but such schemes require femtosecond synchronization between the pump and probe laser pulses. Here, researchers present few-femtosecond timing between a free-electron laser and an external laser exploiting terahertz radiation.
