Integrated injection seeded terahertz source and amplifier for time-domain spectroscopy.

چکیده
We used a terahertz (THz) quantum cascade laser (QCL) as an integrated injection seeded source and amplifier for THz time-domain spectroscopy. A THz input pulse is generated inside a QCL by illuminating the laser facet with a near-IR pulse from a femtosecond laser and amplified using gain switching. The THz output from the QCL is found to saturate upon increasing the amplitude of the THz input power, which indicates that the QCL is operating in an injection seeded regime.

متن کاملIntegration of a Mobile Terahertz Spectroscopic System based on HEB Heterodyne Detection
We are developing a mobile heterodyne terahertz system based on hot electron bolometer (HEB) mixer receivers to both image and obtain spectra from biological samples. An HEB mixer provides unprecedented sensitivity and spectral resolution at terahertz frequencies. We have recently demonstrated a lownoise heterodyne passive imager operating at 0.85 THz [1]. A heterodyned HEB detector integrated ...
متن کاملA Tunable Cavity-Locked Diode Laser Source for Terahertz Photomixing
An all solid-state approach to the precise frequency synthesis and control of widely tunable terahertz radiation by differencing continuous-wave diode lasers at 850 nm is reported in this paper. The difference frequency is synthesized by three fiber-coupled external-cavity laser diodes. Two of the lasers are Pound–Drever–Hall locked to different orders of a Fabry–Perot (FP) cavity, and the thir...
متن کاملHigh-gain Seeded Fel Amplifier Tunable in the Terahertz Range
The lack of a high-power, relatively low-cost and compact terahertz (THz) source in the range 0.3-3x10 Hz is the major obstacle in progressing on biomedical and material studies at these wavelengths. A high-gain, single pass seeded FEL technique allows to obtain high power THz pulses of a high spectral brightness. We describe an ongoing project at the Neptune laboratory where a ~ 1kW seed pulse...
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...
