Generation of broadband THz pulses in organic crystal OH1 at room temperature and 10 K

We studied the effects of cryogenic cooling of a 2-[ 3-(4hydroxystyryl)-5, 5-dimethylcyclohex-2-enylidene] malononitrile (OH1) crystal on the generation of broadband THz pulses via collinear optical rectification of 1350 nm femtosecond laser pulses. Coolin ...

Intense THz radiation produced in organic salt crystals for high-field applications

Christoph Peter Hauri

Organic stilbazolium salt crystals pumped by intense, ultrashort mid-infrared laser have been investigated for efficient THz generation by optical rectification. In this paper we present our latest results in view of the generation of single-cycle and high ...

Multi-octave MV/cm pulses filling the THz gap

Christoph Peter Hauri

Single-cycle THz pulses with electric field strength of MV/cm are required for wide range of applications from physics to biology and medicine [1]. Presently, high fields are still challenging to produce in the THz gap (0.1-10 THz) where important condense ...

Spatiotemporal Focusing Dynamics of Intense Supercontinuum THz Pulses

Christoph Peter Hauri

High-field terahertz (THz) single-cycle pulses with 1.5 MV/cm are generated by optical rectification in the stilbazolium salt crystal 4-N, N-dimethylamino-4'-N'-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate. We show experimentally that the generated ...

Terahertz passive components for Dynamic Nuclear Polarization Nuclear Magnetic Resonance applications

Emile Jacques de Rijk

Terahertz radiation, THz = 1012 Hz, refers to electromagnetic signals with frequencies in the range of 0.3 to 3 THz, and wavelengths between 1 and 0.1 mm. This part of the electromagnetic spectrum is located in between millimeter waves at lower frequencies ...

Laser-driven generation of intense single-cycle THz field

Christoph Peter Hauri, Fernando Ardana Lamas

We report on laser-based, high power single-cycle THz source. The THz radiation is generated by four-wave mixing in plasma and by optical rectification in organic salt crystal pumped by powerful optical parametric amplifier. The first approach permits the ...

Analysis and design of terahertz antennas based on plasmonic resonant graphene sheets

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

Resonant graphene antennas used as true interfaces between terahertz (THz) space waves and a source/detector are presented. It is shown that in addition to the high miniaturization related to the plasmonic nature of the resonance, graphene-based THz antenn ...

Strong-field single-cycle THz pulses generated in an organic crystal

Christoph Peter Hauri, Fernando Ardana Lamas

We present high-power single-cycle carrier-envelope phase locked THz pulses at a central frequency of 2.1 THz with MV/cm electric field strengths and magnetic field strengths beyond 0.3 T. The THz radiation is generated by optical rectification in an organ ...

Towards High-power Single-cycle THz Laser for Initiating High-field-sensitive Phenomena

Christoph Peter Hauri, Fernando Ardana Lamas

Powerful THz radiation confined in one field period or less is an adequate tool for triggering nonlinear actions. We show results towards the realization of a tunable high-power THz source based on a laser-driven frequency conversion scheme in plasma and n ...
