On January 13, 2025, Prof. Ferenc Krausz, the 2023 Nobel Laureate in Physics, visited the Synergetic Extreme Condition User Facility (SECUF) at the Institute of Physics (IOP), Chinese Academy of Sciences (CAS), and Huairou Science City.

In the morning, Prof. Krausz listened to an introduction about Huairou Science City at the MA Building hall on IOP Huairou Campus. He then went to the roof for a panoramic view of the City. Subsequently, he visited experimental facilities such as the femtosecond ultrafast station, attosecond ultrafast station, and ultrafast X-ray dynamics station in Building X7. During the visit, Prof. Krausz highly praised the construction of the experimental facilities and the achievements made. After the tour, under the chairmanship of Prof. Zhiyi Wei, Prof. Krausz held a discussion with researchers and graduate students working on ultrafast systems. They discussed recent advancements and applications in ultrafast lasers. Prof. Krausz expressed strong interest in collaboration and proposed specific cooperative plans. Prof. Krausz also wrote a message with warm wishes.

In the afternoon, Prof. Krausz delivered an academic lecture titled "Can Science Contribute to Addressing the Greatest Challenges of Our Time?" Over 400 attendees from IOP Huairou Campus, institutions in Huairou Science City, and the Beijing Laser Accelerator Innovation Center participated in the event. Before the lecture, Jianxin Wang, Director of the Exchange and Cooperation & Talent Work Office of Huairou Science City Management Committee, gave a welcome speech. Prof. Zhiyi Wei briefly introduced Prof. Krausz's significant academic achievements and presented him with the CAS President’s International Fellowship Initiative (PIFI) Distinguished Scholar Certificate. In his lecture, Prof. Krausz focused on how ultrafast lasers can contribute to extending the healthy lifespan of over 3 billion people in developing countries. He highlighted the application prospects and research progress of ultrafast lasers in preventive medicine, particularly in screening for diseases such as cancer. He also shared his team's work on mid-infrared ultra-broadband few-cycle femtosecond lasers. During the Q&A session following the lecture, Prof. Krausz patiently answered questions from researchers and students.

Prior to the lecture, Xiongjing Lan, Member of the Party Working Committee and Deputy Director of Huairou Science City Management Committee, and Deputy Head of Huairou District, had an in-depth conversation with Prof. Krausz. Prof. Krausz expressed sincere praise for the scientific research environment in Huairou and showed great interest in international collaboration based on scientific infrastructure and platforms.

Prof. Ferenc Krausz specializes in ultrafast lasers, nonlinear optics, atomic physics, plasma physics, and medical physics. His research team generated and measured the world's first attosecond light pulse in 2001, capturing electron motion within atoms, marking the advent of the attosecond era in ultrafast science. Due to this significant contribution, he was awarded the 2023 Nobel Prize in Physics and the 2022 Wolf Prize.
