Optical thin film coating design represents a complex inverse problem traditionally relying on computationally intensive numerical optimization methods. These conventional approaches, exemplified by the widely used Needle Algorithm [1], require significant computational resources and often rely on expert intervention [2]. We here propose a new approach to these challenges and present a physics-informed machine learning framework based on an autoencoder architecture and use it to design an ultra-broadband dispersive mirror.enComputer Science, Information and General Works::006: Special computer methods::006.3: Artificial IntelligenceTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringAI-driven design of high-performance optical thin film coatings for ultrafast lasersConference Paper10.1109/CLEO/EUROPE-EQEC65582.2025.11110889Conference Paper
