Abstract

We demonstrated terahertz wave parametric wavelength conversion between frequency controlled infrared (stabilized pumping and tunable seeding) beams and terahertz wave in a nonlinear crystal. The pumping beam is generated using a PPLN-OPG seeded by a stabilized laser beam as traceable to the national standard. The generated pulses are amplified by a KTA-OPA pumped by a SLM Nd:YAG MOPA system. The wavelength of seeding beam is monitored by a “spectral drill” cavity as intensity error signal. We expect that these methods will open up new fields.
