TERA ASOPS High-Speed THz-TDS

December 15, 2016

High-speed spectroscopic data sampling is an easy task when applying the ASynchronous OPtical Sampling (ASOPS) technique, using two femtosecond lasers at a locked but slightly detuned pulse repetition rate. Each pulse pair cycle, the delay between the optical pump and probe pulses, respectively, is accumulated, resulting in a sweep with the duration of the entire inverse repetition rate. This well-established tool for optical ultrafast spectroscopy is now commercially available at Menlo Systems for Terahertz time-domain spectroscopy (THz-TDS). The novel TERA ASOPS is combining the ASOPS technology with the latest broadband THz devices into a turn-key THz-TDS system where scanning range and speed are no longer limited by mechanically moving parts. A detection window of 10 ns is available for measurements at a revolutionary high rate, while the spectral resolution is pushed into the region of hundreds of MHz. The two ASOPS lasers, based on Menlo Systems’ patented figure 9® mode locking technology for highest stability and reliability, provide the optical pulses for THz emission and detection. Fiber coupled high-power THz modules and high-transmission low-loss polymer optics guarantee broadband performance, easy alignment and long-term stability of the THz path. Despite its complexity, the TERA ASOPS is standing out due to user-friendly operation and measurement software. A fast TCP socket interface allows remote control and high-speed data transfer over network. The range of applications for the TERA ASOPS can be hugely extended by simply adding laser output ports at 1560 and/or 780 nm wavelengths, turning the system into a stand-alone tool for ultrafast optical spectroscopy.
