Menlo Systems' TERA-K15-SYNC fiber-coupled terahertz spectrometer provides a complete solution for fast, broadband, time-domain THz spectroscopy, offering maximum flexibility for scientific THz applications.

The system includes Menlo Systems' latest figure 9® femtosecond laser source with a 1.5 μm emission wavelength, a fiber coupled optical light path with a delay line, a THz wave path with a THz emitter, THz detector and THz optics, control electronics, and a PC with data aquisition and evaluation software.

The delay line offers flexibility by covering a total range of >850 ps, and performs fast scanning up to 20 Hz in relevant time windows. The data acquisition scheme without lock-in amplifier, together with Menlo Systems' high-power fiber coupled terahertz emitter and receiver modules, guarantees high bandwidth and dynamic range with fast scan rates.

For terahertz imaging applications, the TERA Image extension unit can be integrated into the setup, which includes image acquisition and reconstruction software. The ImageLab software, based on multivariate statistical methods, enables the user to analyze and classify acquired hyperspectral THz images.

The system's laser source can be extended by additional laser output ports at 780 nm and 1560 nm. To perform terahertz time domain spectroscopy (THz-TDS) with optical sample excitation at those wavelengths, the TERA-K15-SYNC setup can be upgraded by the THz-Pump-Probe add-on.

Moreover, with the SYNC option, the TERA-K15-SYNC can be synchronized to an external source, such as a synchrotron or a laser source, for which Menlo Systems provides the RRE-SYNCRO locking electronics for the phase lock.
