AB  - Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting and electrospinning. FESEM analysis revealed that the processing with electrospinning enables better dispersion of quantum dots. Time-resolved laser induced fluorescence measurements confirmed uniform size of QDs in fibers with the emission at only one wavelength. Oxidation effects in quantum dots were removed with the use of PMMA as a host, and the core remained active, which was confirmed with FTIR analysis and time-resolved laser induced fluorescence measurements.

AB  - 4 th generation X-ray light sources have attracted enormous attention of scientists from various fields, allowing conducting pump-probe experiments, which can reveal the mechanisms of chemical reactions and processes, occurring on the molecular and atomic level and on the time-scale of few femtoseconds. FLASH (Free Electron Laser in Hamburg) has a world-wide unique ability to generate tunable, broadband, high-field THz pulses, which are synchronized with XUV pulses on the order of few femtoseconds [1, 2]. It opens the door to new exiting THz pump X-ray probe experiments, such as THz driven magnetization and ion dynamics, coherent spin control, etc. For such experiments it’s extremely important to know the properties of the radiation, which is delivered to the experiment; therefore suitable tools for characterization are required. We are presenting a custom made ultra-broadband FTIR Spectrometer (Fourier Transform Infrared), optimised for THz source at FLASH and a 2D beam-profiler, both optimized to detect high-field, broadband THz radiation (0.6 µm to 600 um) and which are used as a part of the THz characterization tool, developed at THz beamline at FLASH. THz characterization tool also includes the Electro-optic Sampling (EOS) set up and Spectral Decoding (EOSD) set up, developed together in collaboration with the Institute of Physics and Vinca Institute of Nuclear Sciences in Belgrade, Serbia. We will also present the experiments, which have been conducted in THz beamline during last couple of years to give an overview on the exiting opportunities for light-matter interaction experiments with such an intense and broadband THz source.

AB  - High-field THz radiation is a fascinating tool to study the interaction of electromagnetic waves with matter, such as demagnetization dynamics [1], tracking the ultrafast motion of a signal molecule [2], resonant control of states of matter [3] and et al. THz beamline at FLASH1 provides both tunable narrow bandwidth (1-30THz) and broad bandwidth intense THz pulses for user's experiment. Recently we have developed a THz characterization tool, optimized for FLASH's THz spectral range. It is based on THz electro-optic (EO) sampling, in combination of EO spectral decoding for THz pulse arrival timing jitter correction. It enables characterization of THz pulse, as a statistical average used in the experiment, with high temporal and spectral resolution. Because of the highly fluctuating nature of the THz generation process at FLASH, for certain class of experiments, knowledge of the individual THz pulse properties is essential. Thus a fast diagnostic of THz parameters is required and single-shot method offers clear advantages. The EO spectral decoding subsystem in the THz pulse characterization tool can be used as independent setup at performing single-shot measurements. However, due to the frequency interference in a long chirped laser pulse, the measured THz temporal profile is almost always distorted [4], particularly when characterizing ultra-broadband THz pulses with realistic probing laser. In order to study this single-shot technique, the broad bandwidth THz dump radiation is measured by EO spectral decoding setup. The distortion is analyzed in details and the measured profiles show agreement with our calculations. The measurements can help us to study possible retrieval strategies of the original THz electric field from the distorted measured one. This as a final goal has a single shot characterization of THz pulses for FLASH user experiments.
