The Optica High-Brightness Sources and Light-Driven Interactions Congress includes three topical meetings that highlight the latest advances in high-brightness sources, attosecond science, light-driven interactions, and mid-IR laser technologies. Specific technical areas that are covered include strong-field phenomena, terawatt and petawatt lasers, high-harmonic generation, laser fusion technologies, compact EUV and X-ray sources and their applications, high-energy and high-intensity IR lasers, and applications of mid-IR and THz sources. The co-location of meetings covering these topics provides a unique opportunity to expand interaction with multidisciplinary groups that share related interests and goals.
