1.2 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-...

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 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 کاملTunable Diode-pumped-lna Laser
Diode-pumped crystals provided recently new compact laser devices. We report the first end pumping of a La Ndl-xMgAEl,Ol,(LNA) crystal using a 200mW diode array (Spectra Diode Lab). We also rgport the first results obtained with a ImW diode (SONY). This C.W. laser can be tuned from 1.048~ to 1.086pm. Without selective elements in the cavity, the laser emits around 1.054pm with a threshold of 24...
