Researchers show how to increase X-ray laser brightness and power using a crystal cavity and diamond mirrors

The long – but not too long – cavity would ping-pong X-ray pulses inside of a particle accelerator facility to help capture nature’s fastest...

August 2, 2023  ·  3 min read
This cartoon figure shows how the cavity-based X-ray free electron laser works in general. The electron beam (blue) travels through an undulator (brown), which causes the beam to release X-ray pulses. These pulses bounce around a set of four mirrors, helping them become coherent, before they continue down the accelerator to experimental halls.
