Optical parametric amplification of phase-stable terahertz-to-midinfrared pulses studied in the time domain

Natsuki Kanda, Nobuhisa Ishii, Jiro Itatani +1

We report optical parametric amplification (OPA) of low-frequency infrared pulses in the intermediate region between terahertz (THz) frequency and mid-infrared (MIR), i.e., from 16…
