International Symposium on Ultrafast Phenomena and THz Waves (ISUPTW), an international symposium, provides a platform for strengthening the collaboration and exchange among worldwide researchers in academia and industry and promoting the development in Ultrafast and Terahertz science and technology. The biennial symposium, initiated in 2002, has been held in Beijing, Shanghai, Nanjing, Tianjin, Xi'an, Wuhan, Chongqing, Changsha and Chengdu. It brings together scholars, researchers, engineers and students from more than 10 countries and typically hosts about 150-400 participants.

ISUPTW 2023 will be hosted by Nankai University in Qingdao at Sep. 8-11, 2023. Two symposia, THz Science and Technology and Ultrafast phenomena, are being arranged in the symposium with the scope ranging from basic research to application, including the fields of terahertz and ultrafast phenomena. Authors of all the presented contributions may choose to publish a conference paper in the conference Proceedings of IEEE (EI indexed) or submit to the peer-reviewed journal, Journal of Light: Science & Application, Ultrafast Science, High Power Laser.

Qingdao, a beautiful seaside city, is located in the southeast part of Shandong Province. To the east, a short distance across the Yellow Sea, lie Korea and Japan, making Qingdao an important city for international trade.
