Andreas Becker

Andreas Becker is a Distinguished Professor of Physics at the University of Colorado Boulder and a Fellow at JILA, a joint institute with NIST. His research focuses on ultrafast phenomena in atoms, molecules, and clusters, particularly attosecond electron dynamics, coherent control, and molecular imaging using intense laser pulses. He develops theoretical methods to analyze interactions between matter and ultrashort (femtosecond/attosecond) laser fields, including high-harmonic generation and ionization processes.

Key achievements include pioneering work on elliptically polarized high-harmonic generation, attosecond streaking time delays, and imaging ring-current wave packets in helium. He leads a collaborative group bridging theory and experiment, supported by grants such as the NSF Physics Frontiers Center (PFC) award. Notable honors include the Optica Fellowship (2023) and CU’s Distinguished Professor title (2021).

His research spans attosecond science, multiphoton processes, and multielectron effects, with applications in XUV to mid-infrared laser technologies. He actively contributes to theoretical frameworks for ultrafast dynamics, emphasizing coherent control and plasma-state evolution. Current projects explore vacuum ultraviolet pulse characterization and spatial chirp effects in harmonic generation.
