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 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-...
متن کاملHigh-power Broadband Organic THz Generator
The high-power broadband terahertz (THz) generator is an essential tool for a wide range of THz applications. Here, we present a novel highly efficient electro-optic quinolinium single crystal for THz wave generation. For obtaining intense and broadband THz waves by optical-to-THz frequency conversion, a quinolinium crystal was developed to fulfill all the requirements, which are in general ext...
متن کاملTHz transmittance measurements of nucleobases and related molecules in the 0.4- to 5.8-THz region using a GaP THz wave generator
An automatic measurement system for terahertz (THz) transmission spectroscopy based on difference-frequency generation (DFG) of widely tunable coherent THz waves via excitation of a phonon–polariton mode in GaP was constructed and improved to give it a wider frequency measurement range and four times greater S/N ratio by using the double-beam method. In this paper, we present spectroscopic meas...
