First announcement

Dear colleague,

On behalf of the International Program Committee, we are pleased to announce that ATTO X, the 10th International Conference on Attosecond Science and Technology will take place on July 6-11, 2025, in Lund, Sweden.

ATTO is the largest and most prestigious international conference in attosecond science and technology, held every two years and covering all aspects of attosecond science and technology, from sources and metrology to applications.

More detailed information about ATTO X will be announced on the conference website as it becomes available. The local organizers can be contacted via e-mail at

Lund is one of Sweden’s oldest cities with over 1000 years of history. The magnificent cathedral from the 12th century and the world-famous university from the 17th century shape the city’s history, culture, knowledge and innovation. Lund is full of contrasts. From quaint cobblestoned streets and old half-timbered houses, to some of the world’s most innovative companies and institutions. In the north-east part of Lund, a new city district is being developed around the two major research facilities MAX IV Synchrotron Laboratory and the European Spallation Source (ESS), and in between them a new Science Village is emerging, with the goal of hosting a large number of infrastructures for research, education, and industry. The ATTO X conference will take you from Science Village, where the first half of the conference is organized, to the old city center of Lund, where the conference dinner and the last sessions of the conference will be held.

We are looking forward to welcoming you all to Lund in 2025!
