STRP-TeraTune
The STRP-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 STRP-TeraTune is based on a flash lamp pumped laser (repetition rate 50 Hz
to 200 Hz) with a special 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 to 20 THz). Terahertz radiation is generated via frequency
mixing in the novel organic nonlinear optical crystal STRP-DSTMS, ideally suited
to achieve highest terahertz conversion efficiency.
The STRP-TeraTune includes all optical, mechanical, electronic
components for the generation of THz waves and software control.
