. These pulses are so intense that they can create "warm dense matter," a state that exists inside giant planets like Jupiter. The laser's immense power allows scientists to capture atomic and molecular processes in unprecedented detail, opening new frontiers in chemistry, materials science, and biology.

The Upcoming Upgrade

The planned upgrade, known as LCLS-II-HE (High Energy), will further enhance the laser's capabilities. The upgrade will increase the maximum energy of the X-ray pulses from 15 to 20 kiloelectronvolts (keV) 2
