Interest of the research in terahertz (THz) wave has been strongly motivated by its wide
applications in the fields of physics, chemistry, biology, and engineering. Develo** …

Relativistic interactions between ultraintense (> 10 18 W cm-2) laser pulses and magnetized
underdense plasmas are known to produce few-cycle Cerenkov wake radiation in the …

Two-color plasma, induced by two lasers of different colors, can radiate ultra-broadband and
intense terahertz (THz) pulses, which is desirable in many technological and scientific …

We study the influence of the polarization states of ionizing femtosecond two-color pulses on
the emitted terahertz radiation in gases. A local-current model and plane-wave evaluations …

Terahertz (THz) emissions from fast electron and ion currents driven in relativistic,
femtosecond laser-foil interactions are examined theoretically. We first consider the radiation …

Terahertz pulse generation by ultraintense two-color laser fields ionizing gases with near-to
far-infrared carrier wavelength is studied from particle-in-cell simulations. For a long pump …

At the selected frequencies from 0.3 to 10 THz we measured the two-dimensional (2 D)
distributions of fluence and polarization of terahertz (THz) emission from a single-color …

We measured and simulated the spectrally resolved angular distributions of 0.3–1-THz
emission from the two-color filament with its plasma length (∼ 40 mm) exceeding the …

In the experiment, the laser pulse (744 nm, 0.5 mJ, 90 fs) focused into the air gap between
the plane electrodes biased by a 10 kV/cm field (DC-biased filament) produced terahertz …

Coherent time-domain spectroscopy (TDS) using terahertz radiation is valuable for
fundamental science, security, and medical applications. This study investigates the …
