We are pleased to announce the 14th edition of the Ultrafast Optics conference (UFO XIV), scheduled to take place from October 5-10, 2025. UFO is the premier international conference focused on the science and technology of generating, manipulating, and measuring ultrafast laser sources. It is independently organized by scientists in the field, with strong support from industrial partners.

Continuing its tradition of being hosted in unique and captivating locations, the next UFO conference will be held in Furnas on São Miguel Island, part of the Azores Archipelago in Portugal. The Azores, known for its dramatic landscapes, charming fishing villages, and vibrant blue hydrangeas, offers the ideal setting for a networking retreat with the ultrafast optics community. As a UNESCO World Heritage Site located in the mid-Atlantic, it provides a perfect backdrop for meaningful exchanges and collaboration.

We hope to see you in the Azores in October 2025. Please feel free to contact us at info@ultrafastoptics2025.org for any inquiries.
