GO-EMON THz wave
Generator consists of the ring cavity, non-collinear phase matched
frequency conversion and wavelength tuning structures. Due to the
ring cavity, GO-EMON achieves the narrow bandwidth of THz
(30-50GHz). The system requires the external pump source (Nd:YAG).
Max rep. rate is 500Hz and it can help to measure the data rapidly.
This system is designed and produced by PAX. Inc. based on the
patented technologies under contract to RIKEN, JAPAN.
