摘要

We report the measurement of the frequency noise power spectral density (FNPSD) of a CO₂ pumped molecular-laser emitting at 2.5THz. The measurement relies on the generation of a beatnote between the THz frequency and the harmonic of the IGHz repetition rate of a fs-fiber comb. We obtain a frequency noise of ~0.1 Hz^{2/Hz at 50kHz, limited by the phase noise of the frequency comb. This shows the potential of (i) molecular lasers as ultra-low phase noise sources of THz radiation, and of (ii) fs-fiber combs, in combination with electro-optic detection, as frequency-agile and low phase-noise THz local oscillators.}
