Continuous soft X-ray pulses with a duration of only 19.2 attoseconds.

Scientists at the Spanish Photonics Research Institute have successfully created soft X-ray pulses with a duration of only 19.2 attoseconds, making it the shortest and brightest soft X-ray pulses ever produced. This achievement is equivalent to creating an "ultrafast camera" that can capture electron dynamics in real time with unprecedented precision, providing a powerful tool for observing microscopic processes that were previously inaccessible. This will greatly advance the development of materials science, quantum technology, and other fields. The related paper has been published in the latest issue of "Ultrafast Science" magazine.
