1 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 کاملTransform-limited, narrow-linewidth, terahertz-wave parametric generator
An injection-seeded nanosecond terahertz ~THz! wave parametric generator was demonstrated using nonlinear crystals that were pumped by a single frequency Nd:yttrium–aluminum–garnet laser. Spectrum narrowing to the Fourier transform limit ~n51.58 THz, Dn,200 MHz! was achieved by injection seeding the idler wave ~near-infrared Stokes!. This resulted in a THz-wave output power ~900 pJ/pulse, .100 ...
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 کاملTabletop terahertz-wave parametric generator using a compact, diode-pumped Nd:YAG laser
We specifically developed a diode-pumped, Q-switched Nd:YAG laser to act as a pump source for a terahertz-wave parametric generator. A single Q-switched laser pulse ~pulse width 12 ns, pulse repetition frequency 40 Hz! produced an output energy of 12 mJ. Utilizing this pump source, we were able to construct a compact ~6503350 mm! terahertz-wave parametric generator using LiNbO3 crystals. We ach...
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-...
