Control of intervalley scattering in Bi$_2$Te$_3$ via temperature-dependent band renormalization Open
The control of out-of-equilibrium electron dynamics in topological insulators is essential to unlock their potential in next-generation quantum technologies. However, the role of temperature on the renormalization of the electronic band st…

Direct evidence of light-induced phase-fluctuations in cuprates via time-resolved ARPES Open
Phase fluctuations are widely accepted to play a primary role in the quench of the long-range superconducting order in cuprates. However, an experimental probe capable of unambiguously assessing their impact on the superconducting order pa…

Time-resolved ARPES with probe energy of 6.0 eV and tunable MIR pump at 250 kHz Open
In this paper, we present a laser source designed specifically for time- and angle-resolved photoemission spectroscopy (TR-ARPES) investigations of light-induced electron dynamics in quantum materials. Our laser source is based on a ytterb…

Complete characterization of a Yb-based OPA at a high repetition rate using frequency resolved optical switching Open
We demonstrate experimentally that frequency resolved optical switching (FROSt) can be used to characterize ultra-broadband pulses at high repetition rates up to 500 kHz. Specifically, we present the complete temporal characterization of a…
Temporal characterization of two-octave infrared pulses by frequency resolved optical switching Open
We present the temporal characterization of infrared pulses with spectra extending from 0.55 to 2.5 μ m by using the frequency resolved optical switching (FROSt) technique. The pulses are obtained by broadening femtosecond pulses at 1.75 μ…
