Giant self-induced transparency of intense few-cycle terahertz pulses in n-doped silicon
O. V. Chefonov, A. V. Ovchinnikov, S. A. Romashevskiy +5
The results of high-field terahertz transmission experiments on n-doped silicon (carrier concentration of cm) are presented. We use terahertz pulses with…
Aligned copper nanorod arrays for highly efficient generation of intense ultra-broadband THz pulses
S. Mondal, Q. Wei, W. J. Ding +9
We demonstrate an intense broadband terahertz (THz) source based on the interaction of relativistic-intensity femtosecond lasers with aligned copper nanorod array targets. For copp…
High field response of gated graphene at THz frequencies
Hadi Razavipour, Hassan A. Hafez, Ibraheem Al-Naib +11
We study the Fermi energy level dependence of nonlinear terahertz (THz) transmission of gated multi-layer and single-layer graphene transferred onto sapphire and quartz substrates.…
Nonlinear imaging and 3D-mapping of terahertz fields with Kerr media
Matteo Clerici, Daniele Faccio, Lucia Caspani +6
We investigate the spatially and temporally resolved four-wave mixing of terahertz fields and optical pulses in large band-gap dielectrics, such as diamond. We show that it is poss…
Counter-propagating frequency mixing with Terahertz waves in diamond
Matteo Clerici, Lucia Caspani, Eleonora Rubino +6
Frequency conversion by means of Kerr-nonlinearity is one of the most common and exploited nonlinear optical processes in the UV, visible, IR and Mid-IR spectral regions. Here we s…
Scaling mechanism for efficient wavelength conversion in laser plasmas
Matteo Clerici, Marco Peccianti, Bruno E. Schmidt +9
Laser-induced ionization is a fundamental tool for the frequency conversion of lasers into spectral regions so far inaccessible, including both extreme ultraviolet and terahertz. T…
