Non-adiabatically changing the frequency of light in a transient microcavity (2009)
Harding, Philip J., Bakker, Huib J., Hartsuiker, Alex, Claudon, Julien, Mosk, Allard P., Gerard, Jean-Michel, ...
We study frequency-resolved femtosecond pump-probe reflectivity of a planar GaAs/AlAs microcavity. About 8 ps after a pump pulse, we observe an excess signal due to a non-adiabatic frequency change...
Novel surface vibrational spectroscopy: Infrared-infrared-visible sum-frequency generation (2001)
Bonn, Mischa, Hess, Christian, Miners, James H., Heinz, Tony F., Bakker, Huib J., Cho, Minhaeng
A novel type of surface vibrational sum-frequency generation spectroscopy is presented that enables a highly specific measurement of the coupling of molecules on surfaces. With this doubly...

Bakker, Huib J., Bonn, Mischa, Cho, Minhaeng, Heinz, Tony F., Hess, Christian, Miners, James H.
Incoherent Mid-Infrared Photon Echoes With Parametrically Downconverted Light (1999)
Sander Woutersen, Mischa Bonn, Uli Emmerichs, Huib J. Bakker
We present a simple method to generate mid-infrared photon echoes, using parametrically downconverted incoherent light. The photon echoes generated in this way enable the study of the dynamics of...
THz electromagnetic emission by coherent infrared-active phonons (1996)
Dekorsy, Thomas, Auer, Holger, Bakker, Huib J., Roskos, Hartmut G., Kurz, Heinrich
Coherent phonons are excited in single-crystal tellurium by above-band-gap excitation with femtosecond laser pulses. Coherent infrared-active lattice vibrations give rise to the emission of...
Time-resolved observation of coherent phonons by the Franz-Keldysh effect (1996)
Cho, Gyu Cheon, Bakker, Huib J., Dekorsy, Thomas, Kurz, Heinrich
We report on the time-resolved observation of coherent optical phonons in GaAs by the Franz-Keldysh effect. This effect leads to a modulation of the optical interband transitions with a nonlinear...
Quantum coherence of continuum states in the valence band of GaAs quantum wells (1996)
Dekorsy, Thomas, Kim, A. M. T., Cho, Gyu Cheon, Hunsche, Stefan, Bakker, Huib J., Kurz, Heinrich, ...
Quantum beats of heavy and light holes in GaAs quantum wells are investigated in femtosecond time-resolved four-wave mixing and transmission experiments as a function of optical excitation energy....
Exceptionally slow dephasing of electronic continuum states in a semiconductor (1995)
Leisching, Patrick, Dekorsy, Thomas, Bakker, Huib J., Kurz, Heinrich, Köhler, Klaus
The coherent excitation of excitonic and continuum Wannier-Stark states in a semiconductor superlattice with femtosecond laser pulses leads to a modulation of both the interband and the intraband...
Emission of submillimeter electromagnetic waves by coherent phonons (1995)
Dekorsy, Thomas, Auer, Holger, Waschke, Christian, Bakker, Huib J., Roskos, Hartmut G., Kurz, Heinrich, ...
We report on the first observation of the emission of electromagnetic radiation from coherent lattice vibrations in a semiconductor. Coherent optical phonons are excited by ultrashort laser pulses in...
Inhomogeneous dynamics in confined water nanodroplets
Dokter, Adriaan M., Woutersen, Sander, Bakker, Huib J.
The effect of confinement on the dynamical properties of liquid water was studied by mid-infrared ultrafast pump–probe spectroscopy on HDO:D2O in reverse micelles. By preparing water-containing...
