Toptica TeraFlash: Time-domain terahertz spectroscopy

Toptica TeraFlash

TOPTICA introduces the new TeraFlash system, a table-top platform for time-domain terahertz spectroscopy. The all-fibre design is based on mature 1.5 µm telecom technology, combining TOPTICA’s established femtosecond fibre lasers and state-of-the-art InGaAs antennas.

Using a highly precise delay stage, the TeraFlash achieves a peak dynamic range of more than 70 dB. Users can choose between a “precisescan” mode and a “fast scan” mode. In “precise scan” mode a bandwidth of 4 THz and a resolution better than 10 GHz are attained. Alternatively, in “fast scan” mode, a pulse trace is acquired in only 50 ms. The fibre-coupled antenna modules can be conveniently arranged, depending on the needs of the experiment. Integrated in the system is TOPTICA’s FemtoFErb 1560, the most compact ultrafast laser on the market. The SAM mode-locked fibre oscillator and the usage of polarization-maintaining fibres ensure a high robustness and alignment-free, “hands-off” operation. The TeraFlash system is a perfect solution for applications such as high-bandwidth spectroscopy (e.g. of explosives or liquid crystals) and industrial process control.
