PRESS RELEASE
TeraFlash Time-domain terahertz spectroscopy platform
Introducing the TeraFlash system, TOPTICA's new table-top platform for time-domain terahertz spectroscopy. The all-fiber design is based on mature 1.5 μm telecom technology, combining TOPTICA’s established femtosecond fiber lasers with 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 “precise scan” or “fast scan” mode. “Precise scan” mode attains a bandwidth of 4 THz and a resolution better than 10 GHz. “Fast scan” mode acquires a pulse trace in only 50 ms. Depending on the requirements of your experiment, you can arrange the fiber-coupled antenna modules conveniently, as needed.
Integrated in the system is TOPTICA’s FemtoFErb 1560, the most compact, ultrafast laser on the market. The Saturable Absorber Mirror (SAM) modelocked fiber oscillator and polarization-maintaining fibers ensure a very robust 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.
