Time-domain terahertz spectroscopy platform
The TeraFlash combines TOPTICA’s FemtoFiber smart laser technology with state-of-theart InGaAs antennas.

TOPTICA introduces the new TeraFlash system, a 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 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 “precise scan” 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 fiber-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 fiber oscillator and the
usage of polarization-maintaining fibers ensure a high robustness and
alignment-free, “hands-off” operation.
The TeraFlash system is a perfect solution for applications such as highbandwidth
spectroscopy (e.g. of explosives or liquid crystals) and industrial
