We review the progress in controlling quantum dynamical processes in the condensed phase with femtosecond laser pulses. Due to its high particle density the condensed phase has both high relevance and appeal for chemical synthesis. Thus, in recent years different methods have … Manipulation of quantum interference requires that the system under control remains coherent, avoiding (or at least postponing) the phase randomization that can ensue from coupling to an uncontrolled environment. We show that closed-loop coherent control can be used to mitigate the rate of quantum dephasing in a gas-phase ensemble of potassium dimers (K2), which acts as a model system … Download Citation | Femtosecond Coherent Control of Quantum Systems in Liquid Phase. | Femtochemistry is a mature field which now moves beyond observing molecular motion, towards laser control … A phase-stable superposition of femtosecond pulses from a compact erbium-doped fiber source and their second harmonic is shown to induce ultrashort ∼μA current bursts in single unbiased GaAs nanowires. Current injection relies on a quantum interference of one- and two-photon absorption pathways. The vector direction of the current is solely dictated the polarization and relative phase of Two-Dimensional Electronic Spectroscopy Can Fully Characterize the Population Transfer in Molecular Systems. J. Chem. Phys. 145, 124312 (2016) 105. Inherently phase-stable coherent two-dimensional spectroscopy using only conventional Adaptive femtosecond quantum control in the liquid phase, In “Ultrafast Phenomena XIII” (R. D In this paper, we present a feasible method to realize and improve the selective excitation of femtosecond coherent anti-Stokes Raman scattering (CARS) in a mixture. We theoretically show that, shaping both the pump and probe pulses with the π phase step, the CARS signal from one quantum system can be enhanced and simultaneously that from the other quantum system is effectively … Femtosecond pulse shaping using a spatial light modulator and degenerate four-wave-mixing (DFWM) spectroscopy have been combined to control the vibrational wave packet motion in the electronic ground and excited states of the prototype molecule K 2 and, thus, study the influence of phase and amplitude modulated pulses on the molecular FWM response. It is shown that the vibrational motion of Some mode-locked diode lasers can generate pulses with femtosecond durations. Directly at the laser output, the pulses durations are usually at least several hundred femtoseconds, but with external pulse compression, much shorter pulse durations can be achieved.Mode-locked semiconductor lasers are also suitable for very high pulse repetition rates, e.g. Tens or even hundreds of gigahertz. This book contains important contributions from top international scientists on the-state-of-the-art of femtochemistry and femtobiology at the beginning of the new millennium. It consists of reviews and papers on ultrafast dynamics in molecular science. In this paper, we experimentally study the selective excitation of two-pulse femtosecond coherent anti-Stokes Raman scattering (CARS) in a mixture of dibromomethane (CH2Br2) and chloroform (CHCl3) adaptive pulse shaping based on genetic algorithm. Second harmonic generation frequency-resolved optical gating (SHG-FROG) traces indicate that the spectral amplitude and phase of the optimal Using a combination of spatial and temporal shaping of optical laser fields, fully coherent spectroscopy and coherent control can be carried out to high order from optical to THz spectral ranges. A single beam with a single femtosecond pulse can be transformed into multiple beams and multiple pulses, reconfigurably under computer control with no human alignment needed, retaining full phase Ultrafast Phenomena XVI Paul B.

Adjacent femtosecond laser pulses may be placed he coherent manipulation of quantum systems on their nat-ural timescales, as a means to control the evolution of a sys-tem, is an important goal for a broad range of science and technology, including chemical dynamics and quantum information science. In … Abstract The phase of an electronic wave function is shown to play an important role in coherent control experiments. using a pulse shaping system with a femtosecond laser, we explore the phase relationships among resonant and off-resonant Raman transitions in Li 2 measuring the phases of the resulting wave packets, or quantum beats.

Due to the broad spectral width of the driving eld, the oscillations are initiated between a ground state and a coherent superposition of excited states, or a wavepacket", rather than a single excited state. Our experiments reveal an intricate dependence of the wavepacket phase on the intensity of laser eld.

Coherent control of isolated atoms and molecules in the gas phase is well-understood and developed since the 1990s, whereas its application to condensed matter is more difficult because its coherence lifetime is shorter. We have recently applied this technique to condensed matter samples, one of which
