Improving signal-to-noise ratios in pump-probe spectroscopy on light-sensitive samples by adapting pulse repetition rates
Matthias C. Velsink, Maksym Illienko, Komal Chaudhary +1
Ultrafast optical pump-probe spectroscopy is a powerful tool to study dynamics in solid materials on femto- and picosecond timescales. In such experiments, a pump pulse induces dyn…
Comparison of round- and square-core fibers for sensing, imaging and spectroscopy
Matthias C. Velsink, Zhouping Lyu, Pepijn W. H. Pinkse +1
Multimode fibers (MMFs) show great promise as miniature probes for sensing, imaging and spectroscopy applications. Different parameters of the fibers, such as numerical aperture, r…
Spatiotemporal focusing through a multimode fiber via time-domain wavefront shaping
Matthias C. Velsink, Lyubov V. Amitonova, Pepijn W. H. Pinkse
We shape fs optical pulses and deliver them in a single spatial mode to the input of a multimode fiber. The pulse is shaped in time such that at the output of the multimode fiber a…
Uniform line fillings
Evangelos Marakis, Matthias C. Velsink, Lars J. Corbijn van Willenswaard +2
Deterministic fabrication of random metamaterials requires filling of a space with randomly oriented and randomly positioned chords with an on-average homogenous density and orient…
