Scaling submillimeter single-cycle transients toward megavolts per centimeter field strength via optical rectification in the organic crystal OH1
We present the generation of high-power single-cycle terahertz (THz) pulses in the organic
salt crystal 2-[3-(4-hydroxystyryl)-5.5-dimethylcyclohex-2-enylidene] malononitrile or OH1.
Broadband THz radiation with a central frequency of 1.5 THz (λ_c= 200?? μm) and high
electric field strength of 440?? kV/cm is produced by optical rectification driven by the signal
of a powerful femtosecond optical parametric amplifier. A 1.5% pump to THz energy
conversion efficiency is reported, and pulse energy stability better than 1% RMS is achieved …
