Robert Krausz

{{short description|Hungarian-German physicist known for his work in ultrafast laser science and attosecond physics.}}

Robert Krausz (born 1965 in Pécs, Hungary) is a Hungarian-German physicist, widely recognized for his pioneering contributions to the field of ultrafast laser science and attosecond physics. He is a leading figure in the generation and application of attosecond pulses, which enable the observation and control of electron dynamics in atoms, molecules, and solids on their natural timescale.

Biography

Robert Krausz was born in 1965 in Pécs, Hungary. He studied physics at Eötvös Loránd University in Budapest, where he received his diploma in 1989. He continued his doctoral studies at the Vienna University of Technology (TU Wien) in Austria, earning his Ph.D. in 1993 under the supervision of Prof. Ferenc Krausz.

Career and Research

After completing his Ph.D., Krausz pursued postdoctoral research at TU Wien, where he played a crucial role in the development of femtosecond and attosecond laser technology. His early work focused on pushing the limits of ultrashort pulse generation, leading to significant advancements in high-power, few-cycle laser pulses.

In the early 2000s, Krausz's research group, initially at TU Wien and later at the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany, achieved a breakthrough in generating attosecond light pulses. These pulses, lasting only a few hundred attoseconds (1 attosecond = 10⁻¹⁸ seconds), are short enough to resolve the motion of electrons within atoms and molecules. This opened up the new field of attosecond science, providing unprecedented tools for studying fundamental processes in quantum mechanics, chemistry, and materials science.

Krausz's key contributions include:

  • Generation of Attosecond Pulses: Developing methods for reliably generating isolated attosecond pulses, a crucial step for their application.
  • Attosecond Streaking and Reconstruction of Attosecond Harmonic Pulses by Fourier-transform (RABBITT): Pioneering techniques to characterize attosecond pulses and to observe and measure electron dynamics in real-time.
  • Attosecond Electron Dynamics: Using attosecond pulses to observe and control electron motion in various systems, including photoionization delays and charge migration in molecules.
  • High-Power, Few-Cycle Lasers: Significant advancements in the technology behind high-intensity, ultrashort laser pulses that are essential for attosecond pulse generation.

Since 2003, Robert Krausz has been a Director at the Max Planck Institute of Quantum Optics and a Professor of Experimental Physics at the Ludwig Maximilian University of Munich (LMU Munich). He heads the attosecond physics group at MPQ, continuing to push the frontiers of ultrafast science.

Awards and Recognition

Robert Krausz's groundbreaking work has been recognized with numerous prestigious awards and honors, including:

  • The Gottfried Wilhelm Leibniz Prize (2006)
  • The King Faisal International Prize for Science (2013, shared with Ferenc Krausz)
  • The Benjamin Franklin Medal in Physics (2020, shared with Ferenc Krausz and Anne L'Huillier)
  • He is a member of several scientific academies.

Selected Publications

Krausz has authored or co-authored hundreds of peer-reviewed scientific publications in leading journals such as Nature, Science, and Physical Review Letters. His work is highly cited and has significantly impacted the fields of optics, atomic physics, and quantum chemistry.
