Webbpolyethylene (LDPE) excited by different THz electric field strengths are shown in Figure 3a. Figure 3b shows that the peak values of the responses were quadratically dependent on the THz electric field, proving the dominance of THzºinduced thirdºorder nonºlinear Kerr effect. Figure 3. Webb1 sep. 2003 · The magneto-optical Kerr effect (MOKE) is a valuable tool in the study of various magnetic properties and electronic structures of materials [4]. Especially the discovery of giant Kerr rotation of about 90° in CeSb created a lot of renewed interest. In a previous report, the optical properties of InSb in THz region were discussed [5].

Webb13 apr. 2024 · For instance, the signal's central frequency can change due to thermal instabilities of the lasers, interactions with acoustic waves, Doppler effect, etc. Moreover, most of commercial BPFs do not offer bandwidths below just a few GHz, and thus they are a sub-optimal solution for narrowband optical signals with bandwidths of a few MHz or … Webb19 okt. 2024 · In past decades, ultrafast spin dynamics in magnetic systems have been associated with heat deposition from high energy laser pulses, limiting the selective access to spin order. Here, we use a long wavelength terahertz (THz) pump–optical probe setup to measure structural features in the ultrafast time scale. We find that complete … dutch masters wikipedia
