TeraTune
The TeraTune? provides a tunable narrowband terahertz source with a tuning
range from 1.5 to 20 THz and a bandwidth of less than 100 GHz. The basic TeraTune? is based on a flash-lamp pumped laser (repetition rate 50 Hz to
200 Hz) with a dedicated optical parametric oscillator (OPO), where one
wavelength is tuned electronically with a special design to keep the bandwidth
below 100 GHz. Other diode pumped laser systems can be offered. The variable
wavelength is calibrated and the THz difference frequency is computer controlled
(tuning range 1–20 THz). Terahertz radiation is generated via frequency mixing in
the novel organic non-linear optical crystal: DSTMS (4-N,N-dimethylamino-4 ?-N ?-
methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate), ideally suited to achieve
highest terahertz conversion efficiency.
The TeraTune? includes all optical, mechanical, electronic components for the
generation of THz waves and software control.
