Precisely tunable continuous-wave terahertz source with interferometric frequency control.
We realized a tunable continuous-wave terahertz source with megahertz frequency resolution. The system is based on optical heterodyning of two near-infrared distributed feedback diode lasers, each laser being stabilized by electronic feedback from a low-finesse quadrature interferometer. The control loop permits precisely linear laser frequency scans over >1200 GHz, and a beat signal linewidth ...
متن کاملTerahertz-wave Parametric Sources
Terahertz waves are the electromagnetic radiation whose frequency ranges from millimeter waves to the far infrared, shown in Figure 1. While both sides of this range have had a long history of research and development, leading to already commercially available sources, detectors, meters, and many additional devices, the terahertz wave range is still in its infancy, representing the last unexplo...
متن کامل1 Terahertz - Wave Parametric Generator ( TPG ) / Pumping source 1 . 1 Injection - seeded THz - wave Parametric Generator
Coherent tunable terahertz (THz) waves were successfully generated using an injection-seeded THz-wave parametric generator (TPG) based on laser light scattering from the A1-symmetry polariton mode of MgO:LiNbO3 crystals. THz-wave spectrum narrowing to the Fourier transform limit was achieved by injection seeding the idler wave (near-infrared Stokes). This resulted in a THz-wave output approxima...
متن کاملTunable terahertz radiation from Stark wave packets.
We investigate the possibility that Stark wave packets can be used as a source of shaped terahertz radiation. Calculations for the sodium atom reveal that the frequency and intensity of the THz emission can be controlled over a broad range by varying the parameters of the excitation pulse.
متن کامل1.2 A tunable injection-seeded terahertz-wave parametric generator using a compact, diode-pumped Nd:YAG laser
We developed a compact (30 cm × 65 cm) tunable injection-seeded terahertz-wave parametric generator (is-TPG) with a diode-pumped Nd:YAG laser that was specially designed for pumping the is-TPG. The pump laser, which produced an output energy of 11 mJ in a single Q-switched pulse with a pulse width of 6 ns, was operated with MgO:LiNbO3 crystals and a seed source for the idler wave. A narrow THz-...
