Terahertz Synthetic FM Triplet for Distortion-Free Stabilization and Lamb-Dip Spectroscopy
Kohei Eguchi, Toki Tanaka, Hiroshi Ito +1
We demonstrate a distortion-free terahertz frequency stabilization technique using a "synthetic FM triplet" to overcome modulation sideband interference associated with high-densit…

Lamb-dip spectroscopy of rotational levels with UTC-PD terahertz emitter
Kohei Eguchi, Takashi Arikawa, Hiroshi Ito +1
Pump-probe saturation spectroscopy in the sub-terahertz region was performed in the rotational transition (J, K) = (16, 0) <- (15, 0) for gas-phase acetonitrile molecules in the co…
