Toptica has introduced its new TeraFlash system, a table-top platform for time-domain terahertz spectroscopy.
The all-fibre design is based on mature 1.5μm telecom technology, combining Toptica’s established femtosecond fibre lasers and InGaAs antennas. Using a precise delay stage, the TeraFlash achieves a peak dynamic range of more than 70dB. Users can choose between a precise scan mode and a fast scan mode. In precise scan mode a bandwidth of 4THz and a resolution better than 10GHz are possible. Alternatively, in fast scan mode, a pulse trace is acquired in only 50ms. The fibre-coupled antenna modules can be arranged, depending on the needs of the experiment.
