International audience; Deactivation of the lowest excited triplet (pi,pi*) state, (3)(pi,pi*), of the cationic water-soluble Cu(II)-5,10,15,20-meso-tetrakis(4-N-methylpyridyl)porphyrin (CuTMpyP4) was studied by femtosecond transient absorption spect

We excite quantum beats in a quantum well using 12 fs optical pulses. The resulting coherent charge oscillation, in the tens-of-tetrahertz range, radiates a corresponding infrared electromagnetic wave which is monitored through heterodyne detection u

Excitation energy transfer steps in membranes of Heliobacillus mobilis were directly monitored by transient absorption spectroscopy with a time resolution of 30 fs under selective excitation within the inhomogeneously broadened bacteriochlorophyll g

A comparison is made between the femtosecond oscillatory kinetics in membranes and in detergent-solubilized reaction centres of the antenna-deficient RCO1 mutant of Rhodobacter sphaeroides. The main features are very similar, both at room temperature

Multicolour near-infrared femtosecond experiments of a genetically modified bacterial reaction centre show that the phase of two excited-state vibrational modes is conserved for a period of picoseconds over a large range of temperatures. The direct v

It is shown that vibrational coherence modulates the femtosecond kinetics of stimulated emission and absorption of reaction centers of purple bacteria. In the DLL mutant of Rhodobacter capsulatus, which lacks the bacteriopheophytin electron acceptor,

Upon population of its excited state, the retinal chromophore in the membrane protein bacteriorhodopsin (bR) undergoes a sudden (less than approximately 10 fs) change in dipole moment, Deltamu, that can be visualized in a direct way by optical rectif

The extension of time-resolved X-ray diffraction to the subpicosecond domain is an important challenge, as the nature of chemical reactions and phase transitions is determined by atomic motions on these timescales. An ultimate goal is to study the st

International audience; Animal embryo development exhibits a complex ensemble of cell movements that are tightly regulated by developmental gene expression. It was proposed recently that mechanical factors may also play an important role during devel

The complex biomechanical events associated with embryo development are investigated in vivo , by using femtosecond laser pulse-induced ablation combined with multimodal nonlinear microscopy. We demonstrate controlled intravital ablations preserving
