Terahertz signatures of ultrafast Dirac fermion relaxation at the surface of topological insulators at room temperature
S. Kovalev, K. -J. Tielrooij, J. -C. Deinert +13
Topologically-protected surface states present rich physics and promising spintronic, optoelectronic and photonic applications that require a proper understanding of their ultrafas…
Broadband bright twin beams and their up-conversion
Maria V. Chekhova, Semen Germanskiy, Dmitri B. Horoshko +5
We report on the observation of broadband (40 THz) bright twin beams through high-gain parametric down-conversion in an aperiodically poled lithium niobate crystal. The output phot…
Mapping of periodically poled crystals via spontaneous parametric down-conversion
G. Kh. Kitaeva, V. V. Tishkova, I. I. Naumova +3
A new method for characterization of periodically poled crystals is developed based on spontaneous parametric down-conversion. The method is demonstrated on crystals of Y:LiNbO3, M…
Terahertz generation in Czochralski grown periodically poled Mg:Y:LiNbO3 via optical rectification
G. H. Ma, G. Kh. Kitaeva, I. I. Naumova +1
Using a canonical pump-probe experimental technique, we studied the terahertz (THz) waves generation and detection via optical rectification and mixing in Czochralski-grown periodi…
