His long-standing mentorship and guidance at the Vienna University of Technology had the greatest impact on Ferenc’s scientific career.
His illuminating lectures on electromagnetism and electron physics at Budapest University of Technology made Ferenc decide to devote his life to research on electrons and light.
Ferenc’s diploma thesis work on picosecond laser pulse measurement, supervised by Prof. Bakos and his coworker Dr. Tibor Juhász at the Budapest University of Technology, granted Ferenc his first encounters with lasers in 1985.
Measured the evolution of the carrier-envelope phase in a mode-locked laser for the first time, develops femtosecond infrared techniques for medical applications
Pushed the frontiers of ultrafast electron diffraction to the time scale of molecular vibrations (< 30fs); advances it with an all-optical THz technique, further towards the 1-fs frontier; studies the atomic-scale foundations of light-matter interaction
Conceived and tested the basic concepts, system components, and architecture of third-generation femtosecond technology; pursues its proof-of-principle demonstration
Advanced electro-optic sampling to telecommunication frequencies; uses sub-femtosecond light-field-driven currents for exploring strong-field phenomena in wide-gap solids
Made seminal contributions to devising third-generation fs technology and to creating the first petawatt-scale few-cycle laser; will use it for high-energy attosecond pulse generation
Has been pushing the frontiers of broadband dispersive multilayer optical technology towards broader (> octave) bandwidth and into new (UV, IR) wavelength ranges
Demonstrated ultrahigh-average-power (>100 kW) fs pulses, advanced coherent XUV and MIR sources to unprecedented performance levels; develops a novel MIR fs spectroscopy technique
Pioneered high-power fs Yb:YAG thin-disk oscillators, demonstrated their Kerr-lens mode-locking and carrier-envelope-phase stabilization; extends the technology to the mid-IR
Observed a delay in atomic photoemission and bandgap dynamics in Si, both on the attoseond scale; explores strong-field processes in solids with attosecond spectroscopy
Developed the world’s most powerful few-cycle source, uses it for laser-plasma electron acceleration and high-energy attosecond pulse generation
Developed powerful theoretical methods for accessing microscopic motions in attosecond measurements; studies theoretical femtosecond-attosecond strong-field phenomena in solids
Employed genetic, molecular and microscopy tools to study how cells divide and become different from each other by cell polarization in diverse animal model systems in vivo. Currently tackles molecular mechanisms of cancerous growth by broadband infrared spectroscopy.
Generated the first controlled light waveforms (in Vienna) and initial efforts towards their optical parametric amplification (in Garching); explores attosecond phenomena with mid-infrared light
Pioneered theoretical studies on few-cycle pulse generation from solid-state lasers and their use for strong-field interactions (in Vienna); studies attosecond and strong-field processes in condensed matter
Performed, together with Reinhard Kienberger, the first measurement of an isolated sub-femtosecond pulse
Developed a novel high-power sub-picosecond thin-disk laser technology, which now serves as a basis for third-generation femtosecond technology
Explored (theoretically and experimentally) novel routes to generating powerful attosecond pulses from relativistic interaction
Pioneered the generation of few-cycle pulses and their use for XUV continuum generation as a forerunner for isolated attosecond pulse generation
Demonstrated the first femtosecond laser using chirped mirrors for dispersion control and advanced this laser to the #1 femtosecond titanium-sapphire oscillator of the world (Rainbow)
Led the development of the prototype of second-generation attosecond beamlines (AS-1@ MPQ) and used it for real-time observation of electron tunneling
Initiated the first attosecond laboratory in the Arabic world and a new collaboration with Ferenc’s group aiming at the use of infrared lasers for early cancer detection
Pioneered theoretical modelling of attosecond electron processes, including, among others, a delay in photoemission
Proposed the concept behind the attosecond streak camera, which was demonstrated in Ferenc's laboratory in Vienna at the turn of the millennium.

Performed the first attosecond spectroscopy experiment in the Vienna laboratory
His self-referencing technique for frequency-comb stabilization played a central role in the generation of the first waveform-controlled light in Vienna in 2003
Pioneered thin-disk ytterbium laser technology for amplifying 1-picosecond-scale pulses to kilowatt average power levels at kilohertz pulse repetition rates.

Developed the first XUV multilayer optics for the isolation of a single attosecond pulse and, later, for compensating its chirp (first in Vienna and later at LAP)

Generated and measured the first subfemtosecond pulse, demonstrated the first attosecond streak camera, measured first sub-femtosecond X-ray FEL pulses; explores attosecond electron transport in solids
Demonstrated attosecond electron control in a molecule for the first time and pioneered attosecond nanoplasmonics; explores collective electron phenomena in nanoscopic systems
