چکیده
6 techniques. Of particular interest is the early response of the molecule and the 7 solvent, which is difficult to study due to the ambiguity in assigning and differ8 entiating interand intra-molecular contributions to the electronic and vibrational 9 populations and coherence. Our measurements compare the yield of fluorescence 10 for two laser dyes IR144 and IR125 as a function of chirp. While negatively chirped 11 pulses are insensitive to solvent viscosity, positively chirped pulses are found to be 12 uniquely sensitive probes of solvent viscosity.

Solvent Environment Revealed by Positively Chirped Pulses.
The spectroscopy of large organic molecules and biomolecules in solution has been investigated using various time-resolved and frequency-resolved techniques. Of particular interest is the early response of the molecule and the solvent, which is difficult to study due to the ambiguity in assigning and differentiating inter- and intramolecular contributions to the electronic and vibrational popul...
متن کاملToward elucidating the mechanism of femtosecond pulse shaping control in photodynamics of molecules by velocity map photoelectron and ion imaging.
The control of photofragmentation and ionization in a polyatomic molecule has been studied by femtosecond chirped laser pulse excitation and velocity map photoelectron and ion imaging. The experiments aimed at controlling and investigating the photodynamics in CH(2)BrCl using tunable chirped femtosecond pulses in the visible wavelength region 509-540 nm at maximum intensities of about 4x10(13) ...
متن کاملNumerical Simulation of an Intense Isolated Attosecond Pulse by a Chirped Two-Color Laser Field
We investigate theoretically the high-order harmonic spectrum extension and numerical generation of an intense isolated attosecond pulse from He+ ion irradiated by a two-color laser field. Our simulation results show that the chirp of the fundamental field can control HHG cutoff position. Also, these results show that the envelope forms of two fields are important factors for controlling the re...
متن کاملLinear compression of chirped pulses in optical fibre with large step-index mode area.
The possibilities and limitations of linear compression of positively chirped pulses in the negative-dispersion region of a step-index large mode-area single-mode optical fibre are investigated for the first time. Analytical formulae for critical values of radiation power are found, below which pedestal-free pulse compression is possible down to the Fourier limit. It is demonstrated that at rad...
متن کاملCoherent Control of Bond Making.
We demonstrate coherent control of bond making, a milestone on the way to coherent control of photoinduced bimolecular chemical reactions. In strong-field multiphoton femtosecond photoassociation experiments, we find the yield of detected magnesium dimer molecules to be enhanced for positively chirped pulses and suppressed for negatively chirped pulses. Our ab initio model shows that control is...
