High-resolution Doppler-free molecular spectroscopy with a continuous-wave optical parametric oscillator
E. V. Kovalchuk, D. Dekorsy, A. I. Lvovsky +4
We present a reliable, narrow linewidth (100 kHz) continuous-wave optical parametric oscillator (OPO) suitable for high-resolution spectroscopy applications. The OPO is based on a…
An ultra-sensitive pulsed balanced homodyne detector: Application to time-domain quantum measurements
H. Hansen, T. Aichele, C. Hettich +4
A pulsed balanced homodyne detector has been developed for precise measurements of electric field quadratures of pulsed optical quantum states. A high level of common mode suppress…
Quantum state reconstruction of the single-photon Fock state
A. I. Lvovsky, H. Hansen, T. Aichele +3
We have reconstructed the quantum state of optical pulses containing single photons using the method of phase-randomized pulsed optical homodyne tomography. The single-photon Fock…
