We propose a novel, to our knowledge, method for modulating and real-time monitoring of the carrier-envelope phase (CEP) terahertz (THz) pulses. CEP is an essential parameter in interaction THz waves with matter due difference temporal symmetry when carrier extended several cycles. can be continuously modulated at full range high speed by oscillating optical path length Michelson interferometer under 1 µm, as confirmed electro-optic (EO) sampling. The proposed combined data acquisition that links experimental parameters measurements individual high-repetition pulses realize robust modulation measurements. As system does not require EO sampling but only extracts dependence, trend toward ultrafast physical property control observation using will spread other fields.

Abstract Innovation in microscopy has often been critical advancing both fundamental science and technological progress. Notably, the evolution of ultrafast near-field optical nano-spectroscopy nano-imaging unlocked ability to image at spatial scales from nanometers ångströms temporal nanoseconds femtoseconds. This approach revealed a plethora fascinating light-matter states quantum phenomena, including various species polaritons, phases, complex many-body effects. review focuses on working principles state-of-the-art development tip-enhanced microscopy, integrating diverse pump-probe methods across terahertz (THz) ultraviolet (UV) spectral ranges. It highlights their utility examining broad range materials, two-dimensional (2D), organic molecular, hybrid materials. The concludes with spatio-spectral-temporal comparison techniques, within already well-defined domains, offering an outlook future developments tip-based potential address wider

The ultrafast manipulation of molecular states by charge transfer is essential for characterizing and controlling dynamics. In this study, we demonstrated exciton formation in a single molecule through electron tunneling processes between metal tip scanning microscope (STM) using phase-controlled terahertz (THz) pulse. pronounced luminescence the well-defined system under distinct carrier-envelope phase THz pulse revealed that sequential state-selective electron-tunneling to frontier orbitals promoted at STM junction. Furthermore, control was achieved phase- delay-controlled pairs, providing route regulation dynamics emergence new functions.

A terahertz scanning tunneling microscope (THz-STM) is an STM that allows us to perform time-resolved measurements of currents with high temporal resolution, in addition the spatial resolution STMs. In such a device, it necessary guide THz beam tip, which can be difficult if there are tight space restrictions due experimental requirements, as ultra-high vacuum and magnetic fields. We aim develop THz-STM measure fields at cryogenic temperatures time on order picoseconds. this paper, we placed specially designed chamber containing homemade head inside superconducting magnet performed current between Pt–Ir tip highly oriented pyrolytic graphite (HOPG) sample. To introduce pulse into chamber, used narrow pipe waveguide evaluated better than 1 ps, suggests realization for multi-extreme conditions picosecond possible.

Coupling subcycle THz pulses to a scanning tunneling microscope (STM) enables ultrafast spectroscopy at the atomic scale. This technique critically depends on shape of near-field waveform in tunnel junction. We characterize electric field STM junction by electro-optic sampling tip-scattered light (
