Abstract

We demonstrated frequency controlled terahertz wave generation based on parametric wavelength conversion in a nonlinear MgO:LiNbO3 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 seeding beam is monitored and controlled by a “spectral drill” cavity. The frequency of seeding beam is observed as intensity error signal. We expect that these methods will open up new fields.
