LCLS SASE v. Seeded Pulse

Caption

The LCLS’s new self-seeding improvements yield laser pulses focused to higher intensity in a much narrower band of X-ray wavelengths, as you can see in these spectrographs comparing a normal SASE (self-amplified spontaneous emission) pulse (left) and a seeded one (right). The results promise to speed research discoveries and may enable experiments that have never before been possible.
