Strongly coupled coherent phonons in single-layer MoS
C. Trovatello, H. P. C. Miranda, A. Molina-Sánchez +15
We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution (20fs) which is ideally suited to trigger and de…
Broadband optical parametric amplification by two-dimensional semiconductors
Chiara Trovatello, Andrea Marini, Xinyi Xu +11
Optical parametric amplification is a second-order nonlinear process whereby an optical signal is amplified by a pump via the generation of an idler field. It is the key ingredient…
A Hyperspectral Microscope based on an Ultrastable Common-Path Interferometer
A. Candeo, B. E. Nogueira de Faria, M. Erreni +5
We introduce a wide field hyperspectral microscope using the Fourier-transform approach. The interferometer is based on the Translating-Wedge-Based Identical Pulses eNcoding System…
Multi-channel lock-in based differential front-end for broadband Raman spectroscopy
A. Ragni, G. Sciortino, M. Sampietro +5
In Broadband Stimulated Raman Spectroscopy, the intrinsic limit given by the laser shot noise is seldom reached due to the electronic noise of the front-end amplifier and the inten…
Tracking Attosecond Electronic Coherences Using Phase-Manipulated Extreme Ultraviolet Pulses
Andreas Wituschek, Lukas Bruder, Enrico Allaria +31
The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promi…
Excitonic and lattice contributions to the charge density wave in 1T-TiSe revealed by a phonon bottleneck
Hamoon Hedayat, Charles J. Sayers, Davide Bugini +10
Understanding collective electronic states such as superconductivity and charge density waves is pivotal for fundamental science and applications. The layered transition metal dich…
Photocatalytic activity of exfoliated graphite-TiO nanocomposites
Gloria Guidetti, Eva A. A. Pogna, Lucia Lombardi +16
We investigate the photocatalytic performance of nanocomposites prepared in a one-step process by liquid-phase exfoliation of graphite in the presence of TiO nanoparticles (NPs…
Hot electrons modulation of third harmonic generation in graphene
G. Soavi, G. Wang, H. Rostami +8
Hot electrons dominate the ultrafast (fs-ps) optical and electronic properties of metals and semiconductors and they are exploited in a variety of applications including phot…
Coherent anti-Stokes Raman Spectroscopy of single and multi-layer graphene
A. Virga, C. Ferrante, G. Batignani +5
We report stimulated Raman spectroscopy of the G phonon in both single and multi-layer graphene, through Coherent anti-Stokes Raman Scattering (CARS). The signal generated by the t…
Band-edge Excitation of Carotenoids Removes S* Revealing Triplet-pair Contributions to the S1 Absorption Spectrum
Daniel W Polak, Andrew J Musser, George A Sutherland +7
The nature of the low-lying electronic states in carotenoids has been debated for decades. We use excitation-dependent transient absorption spectroscopy and comparison with publish…
