abstract = {We demonstrate high resolution, three-dimensional OCT imaging with a high speed, frequency swept 1300 nm laser source. A new external cavity semiconductor laser design, optimized for application to swept source OCT, is discussed. The design of the laser enables adjustment of an internal spectral filter to change the filter bandwidth and provides a robust bulk optics design. The laser generates ~30 mW instantaneous peak power at an effective 16 kHz sweep rate with a tuning range of ~133 nm full width. In frequency domain reflectometry and OCT applications, 109 dB sensitivity and ~10 $\mu$m axial resolution in tissue can be achieved with the swept laser. The high imaging speeds enable three-dimensional OCT imaging, including zone focusing or C-mode imaging and image fusion to acquire large depth of field data sets with high resolution. In addition, three-dimensional OCT data provides coherence gated en face images similar to optical coherence microscopy (OCM) and also enables the generation of images similar to confocal microscopy by summing signals in the axial direction. High speed, three-dimensional OCT imaging can provide comprehensive data which combines the advantages of optical coherence tomography and microscopy in a single system.},

The laser uses a fiber coupled, semiconductor amplifier and a tunable fiber Fabry-Perot filter. We present scaling principles which predict the maximum frequency sweep speed and trade offs in output power, noise and instantaneous linewidth performance. The use of an amplification stage for increasing output power and for spectral shaping is discussed in detail. The laser generates ~45 mW instantaneous peak power at 20 kHz sweep rates with a tuning range of ~120 nm full width. In frequency domain reflectometry and OCT applications the frequency swept laser achieves 108 dB sensitivity and ~10 {\textmu}m axial resolution in tissue. We also present a fast algorithm for real time calibration of the fringe signal to equally spaced sampling in frequency for high speed OCT image preview.},

abstract = {The early steps in the photocycle of the bacterial proton pump proteorhodopsin (PR) were analyzed by ultrafast pump/probe spectroscopy to compare the rate of retinal isomerization at alkaline and acidic pH values. At pH 9, the functionally important primary proton acceptor (Asp97, pKa = 7.7) is negatively charged; consequently, a reaction cycle analogous to the archaeal bacteriorhodopsin (BR) is observed. The excited electronic state of PR displays a pronounced biphasic decay with time constants of 400 fs and 8 ps. At pH 6 where Asp97 is protonated a similar biphasic decay is observed, although it is significantly slower (700 fs and 15 ps). The results indicate, in agreement to similar findings in other retinal proteins, that also in PR the charge distribution within the chromophore binding pocket is a major determinant for the rate and the efficiency of the primary reaction. }

abstract = {The electron transfer (ET) from organic dye molecules to semiconductor-colloidal systems is characterized by a special energetic situation with a charge transfer reaction from a system of discrete donor levels to a continuum of acceptor states. If these systems show a strong electronic coupling they are amongst the fastest known ET systems with transfer times of less than 10 fs. In the first part a detailed discussion of the direct observation of an ET reaction with a time constant of about 6 fs will be given, with an accompanying argumentation concerning possible artifacts or other interfering signal contributions. In a second part we will try to give a simple picture for the scenario of such superfast ET reactions and one main focus will be the discussion of electronic dephasing and its consequences for the ET reaction. The actual ET process can be understood as a kind of dispersion process of the initially located electron into the colloid representing a real motion of charge density from the alizarin to the colloid.},

  abstract={This study investigates the systems alizarin as well as coumarin 343 coupled onto TiO/sub 2/ nanoparticles with a femtosecond pump/probe setup. The investigation applies sub 20 fs pump pulses, provided by a noncollinear optical parametric amplifier (NOPA) and a supercontinuum generated in CaF/sub 2/ for a ultrabroadband detection covering a spectral range from 300-960 nm. This work also studies coherent wavepacket propagation succeeding electron transfer at the two systems alizarin/coumarin on TiO/sub 2/. Due to the superfast time scale of the investigated electron transfer (ET) reactions of about 4-7 fs the systems show fundamental differences to conventional molecular ET systems. The ET process is no longer mediated by molecular vibrations and therefore classical molecular ET theories lose their applicability. Results show the real-time coherent excitation of molecular vibrational eigenmodes directly by the ET reaction as well as the generation of phonons during polaron formation in the TiO/sub 2/ lattice. The presented investigations in combination with the classification of the appearing mechanisms could be the basis for an extension of molecular ET theories to superfast systems typically found at molecule/solid state interfaces.},

abstract = {Investigations on the ultrafast electron injection and recombination mechanism from the dyes alizarin and coumarin 343 to wide band gap semiconductor colloids in solution are presented, combined with detailed studies on population, depopulation and relaxation phenomena. We discuss transient absorption measurements on time scales from 100 fs to >1 ns throughout the visible spectral range (350–650 nm), allowing the simultaneous time resolved observation of signals assigned to ground state, cation and injected electron in the conduction band of the semiconductor. Analysis of transient absorption changes in the near UV region, where cation absorption is dominant, allows unambiguous assignment of the various kinetic components. This facilitates the distinction between the different contributions of the various absorbing species also in the congested visible spectral range. Comparison between the two dyes with respect to their different electron transfer parameters provides a direct way to analyze the influence of the electronic coupling element V on the injection and recombination process. Detailed inspection of the decay related spectra for both samples yields information on the environmental response succeeding the cation formation.}
