Terahertz laser velocity modulation spectroscopy of ions

چکیده
Velocity modulation spectroscopy has been investigated in the terahertz region, employing pure rotational transitions of ArH and rotation-tunneling transitions of H3O + to study the competition between pressure broadening and Doppler broadening on the lineshapes, neutral suppression, and modulation efficiency. Velocity modulation is demonstrated to be effective to frequencies as low as 60 cm , yielding S/N values for ArH (770/1) that surpass published terahertz FM results by an order

متن کاملPrecision cavity enhanced velocity modulation spectroscopy
The new technique of cavity enhanced velocity modulation spectroscopy has been further developed, incorporating a tighter cavity to laser lock and an optical frequency comb for absolute frequency calibration. Several N2 transitions have been observed with much higher precision than previously possible, and transitions that were blended in earlier Doppler-limited experiments are now resolved. Th...
متن کاملAn ion-implanted InP receiver for polarization resolved terahertz spectroscopy.
We report on the construction, optical alignment and performance of a receiver which is capable of recording the full polarization state of coherent terahertz radiation. The photoconductive detector was fabricated on InP which had been implanted with Fe(+) ions. The device operated successfully when it was gated with near infrared femtosecond pulses from either a Ti:sapphire laser oscillator or...
متن کاملTerahertz magneto-optical polarization modulation spectroscopy
We report the development of new terahertz (THz) techniques for rapidlymeasuring the complex Faraday angle in systems with broken time-reversal symmetry. Using the cyclotron resonance of a GaAs two-dimensional electron gas in a magnetic field, we have tested the performance of the techniques. We have made polarization modulation, high sensitivity (<1 mrad) narrowband rotation measurements with ...
متن کاملFrequency modulation spectroscopy with a THz quantum-cascade laser.
We report on a terahertz spectrometer for high-resolution molecular spectroscopy based on a quantum-cascade laser. High-frequency modulation (up to 50 MHz) of the laser driving current produces a simultaneous modulation of the frequency and amplitude of the laser output. The modulation generates sidebands, which are symmetrically positioned with respect to the laser carrier frequency. The molec...
