Photofragmentation of DCl+ ions alternatively leads to the formation of D+ + Cl or Cl+ + D in competing reaction channels. The branching ratio of the product yields D+/Cl+ has been investigated theoretically by numerically solving coupled time depend

The dissociative ionization of deuterium chloride (DCl) has been investigated by employing femtosecond laser pulses at 805 nm. The product branching ratio D(+)/Cl(+) of the fragments D(+) and Cl(+) is strongly affected by the chirp alpha of the laser

We present results of experimental work in which the coherent-control technique has been applied to study the coherent manipulation of excitonic polarization in ZnSe quantum-well samples. We will introduce the linear control of excitonic polarization

The decay of excitonic and biexcitonic polarization in a ZnSe single-quantum well is studied in transient, time-integrated four-wave-mixing measurements. The acoustic- and optical-phonon-scattering coefficients are obtained from the temperature depen

The optical coherent-control technique is used to study biexcitonic effects in the four-wave-mixing signal of a ZnSe single quantum well. The signal is analyzed in both directions 2k1 − k2 and 2k2 − k1 which are not equivalent if a pulse pair is

The time-averaged polarization angles of excitonic and biexcitonic four-wave-mixing signals are investigated in spectrally resolved measurements for different angles between the linear excitation polarizations, delay times and pulse energies. For an

The optical coherent control of the exciton–biexciton system is studied in four-wave-mixing (FWM) experiments on a ZnSe single-quantum well. Coherent control is achieved by applying a pair of phase-locked laser pulses which produce an FWM signal in

The role of excitonic excitations in wide-gap II-VI and nitride semiconductors is reviewed with focus on the recent research at Bremen University. More-particle excitations such as trions and biexcitons are studied including their contributions to no

Temporal coherent-control experiments have been carried out on ZnSe quantum-well structures. We report on the transient four-wave-mixing (FWM) as well as on pump-and-probe (PP) experiments using, in both cases, a sequence of two phase-locked pulses a
