TERA SYNC has been developed for scientific THz applications which need additional multicolor laser output ports and synchronization of the laser repetition rate to an external source. The system includes a fiber coupled THz path and additinal high-power laser output ports for different output wavelengths.

Our new THz TDS system is using one of our scientific platform lasers with an intracavity actuator for tuning of the cavity length. The laser is based on our novel all-PM fiber figure 9® technology for reliable and stable performance, operating at 1.5 µm to serve our fiber coupled high power THz antennas. Optionally, with an integrated second harmonic generation stage the additional laser output ports can be flexibly configured to 780 nm or 1560 nm. For THz-TDS with optical sample excitation the TERA SYNC setup can be upgraded by our THz-Pump-Probe add-on. To accomplish the task of synchronizing the laser with an external source we offer our solution RRE-SYNCRO locking electronics.
