TERA ASOPS
(High-Speed THz Time-Domain Spectrometer)

High-Speed THz Time-Domain Spectrometer
With the ASOPS technique ultrafast data sampling is no longer limited by the natural restrictions of a mechanically moving optical delay unit.
The novel TERA ASOPS highspeed THz time-domain spectrometer system is using this technique to temporally scan THz pulse traces at a revolutionary high rate.
At the same time it is extending the detection window to nanoseconds pushing the spectral resolution into the region of hundreds of MHz.
TERA ASOPS is using two ultrafast lasers operating at a locked repetition rate with a tunable difference, providing the optical pulses for THz emission and detection.
The lasers are featuring Menlo Systems’ patented figure 9® mode locking technology for highest stability and reliability.
The laser pulses are delivered via optical fiber to the THz antenna modules which are of the latest standard for high-power THz wave emission.
A robust, plug-and-play off axis parabolic mirror terahertz optics ensures the highest bandwidth and long term stability of the THz signal for the TERA ASOPS.
For seamless integration into existing experiments, the software features remote control of the spectrometer and high-speed data transfer over network.
On request, additional laser output ports at 1560 nm and 780 nm can be configured.
