چکیده
. . .. . . ._ .. , _.. I We investigate a mechanism responsible for the observed very short times of the photon echo decay (of the order of a.few femtoseconds) . in semiconductors. It is associated with the loss of phase . . memory . , as a result of interaction of the mixed state (associated with interband transitions) with an unscreened random Coulomb potential of the photocarriers or with a random static potential of the impurities.

Electronic dephasing in nonpolar room temperature liquids: UV photon echo pulse duration dependent measurements
The homogeneous dephasing times, T2 , were obtained for the nonpolar chromophore diphenyl acetylene ~DPA! dissolved in the room temperature nonpolar solvents 2-methyl pentane ~2MP! and cyclohexane. The dephasing times were determined by comparing the pulse duration dependent resonant enhancement of the total two pulse four wave mixing signal to a numerically evaluated theory. Data was taken wit...
متن کاملFemtosecond Photon Echo Spectroscopy in Single Laser Shot
We take advantage of extreme spatial thinness of 100-femtosecond pulse of an amplified femtosecond laser and measure for the first time the homogeneous spectrum of a strongly inhomogeneously-broadened solid with a single laser shot. This is achieved by combining causality-related diffraction asymmetry of twoand three-pulse photon echo with oblique excitation pulse wave fronts, which are creatin...

متن کاملFemtosecond up-conversion technique for probing charge transfer
We report on an experimental study of the charge transfer dynamics in a P3HT : PCBM blend by means of a femtosecond fluorescence up-conversion technique. Using two-photon excitation we probe the exciton dynamics in P3HT and a P3HT : PCBM blend with a weight ratio of 1 : 1 at excitation densities of up to 6 × 1018 cm−3. In both samples we find strongly nonexponential decay traces compatible with...
متن کاملThree-photon absorption spectra of zinc blende semiconductors: theory and experiment.
We calculate the spectrum of three-photon absorption (3PA) in zinc blende semiconductors using Kane's four-band model. We apply this to ZnSe and measure the 3PA spectrum using femtosecond pulses, obtaining excellent agreement. The spectrum shows the apparent onset of 3PA from the split-off band and also shows quantum interference between the several possible evolution pathways when exciting car...
