Product information "THzTDS-1000 Terahertz Time Domain Spectrometer"

Spectral Bandwidth 0.2-6 THz; Peak Dynamic Range >50 dB @3.5 THz; Frequency Resolution <10, <35 GHz; Total Scan Duration >100 ps; 760x610x150, 300x300x150 mm

Unlike most time-resolved THz spectrometers in the market employing photoconductive antennas, OZ Optics' THzTDS-1000 system utilizes nonlinear propagation in electro-optic crystals together with proprietary phase matching techniques to generate and detect phase-locked THz pulses.

The THzTDS-1000 system utilizes a compact femtosecond laser (1064 nm wavelength, 40 MHz repetition rate) integrated with OZ Optics’ pulse compressor to obtain a much higher THz bandwidth than other commercially available THz spectrometers for a competitive price. While most THz systems can only resolve frequencies >3 THz by averaging over numerous waveforms, the THzTDS-1000 achieves this bandwidth in a single trace when performing electro-optic sampling with the system’s stepper mode. Better spectral performances can be obtained with the fast continuous scanning option.

This compact spectrometer allows for reliable material characterization in the THz range that is generally only accessible using expensive and bulky ultrafast lasers, and thin electro-optic crystals. An enclosure allows a purge gas to remove water vapor and prevent absorption lines in the THz spectrum while also improving overall signal-to-noise ratio. The software provided with this device allows easy change of measurement parameters and scanning methods based on experiment requirements.
