“…1) separated by time r. A precision translation stage in combination with a ceramic piezo transducer (PZT) enable accurate control of the delay between the pulses of a pulse pair. Phase-locking of time-separated femtosecond laser pulses was achieved by monitoring the electric field interferences through a narrow band monochromator [19,20]. The obtained spectral interference pattern is the Fourier transform of the pulse pair and thus directly reflects the phase difference and delay between the pulses.…”

Phase-locked heterodyne detected pump-probe experiments are reported on solutions of a dye molecule in ethylene glycol, methanol and acetonitrile. By performing experiments at different phase-lock wavelengths, the real and imaginary parts of the line broadening function g(t) could be mapped out. The imaginary part of g(t) is directly related to dissipative dynamics. Comparison of the experimental data with calculations based on the Brownian oscillator model yields soivation frequencies that are substantial higher than those reported using MD simulations on similar systems.

“…(3) that for perfectly collinear pulses, the relative phase varies only temporally (depends only on τ 's) but does not vary spatially (does not depend on r) and as τ 's are scanned a 2D temporal fluorescence interferogram is resulted. This is precisely the reason for using collinear pulses in linear [33][34][35] and nonlinear [29][30][31][32] FDCS experiments.…”

We present a novel experimental scheme for two-dimensional fluorescence-detected coherent spectroscopy (2D-FDCS) using a non-collinear beam geometry with the aid of "confocal imaging" of dynamic (population) grating and 27-step phase-cycling to extract the signal. This arrangement obviates the need for distinct experimental designs for previously developed transmission detected non-collinear two-dimensional coherent spectroscopy (2D-CS) and collinear 2D-FDCS. We also describe a novel method for absolute phasing of the 2D spectrum. We apply this method to record 2D spectra of a fluorescent dye in solution at room temperature and observe "spectral diffusion."

“…Both phases could be set independently at 0 or /2 ͑or any other value͒ and were kept constant at any delay t 12 , t 34 using tracking feedback loops. 35,36 Furthermore, active stabilization of the interferometers prevented phase drifts caused by low-frequency acoustic or thermal perturbations.…”

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. Download date: 21-04-2019Mode suppression in the non-Markovian limit by time-gated stimulated photon echo It is demonstrated that enhanced mode suppression in stimulated photon echo experiments can be obtained by diagonal time gating of the echo. This technique is especially important when the optical dynamics of the system is non-Markovian. A two-mode Brownian oscillator model is used to analyze the effect of time gating on the stimulated photon echo. The method is demonstrated on a dye solution of DTTCI in ethylene glycol at room temperature. Experimentally, time gating of the echo is accomplished by means of femtosecond phase-locked heterodyne detected stimulated photon echo. The vibrational dynamics in this system are explored by conventional stimulated photon echo experiments. Especially stimulated photon echo-maximum shift measurements are found to be particularly useful.
