Closed-loop frequency stabilization-'laser locking'-is required for laser cooling, precision spectroscopy and atomic clocks. We compare the modulation transfer with the direct modulation in signal intensity and noise. By calculating, we get the conclusion that the ratio of signal intensity between modulation transfer scheme and the direct modulation scheme is 1.13:1 whereas the SNR of the ...

Magnetic-enhanced modulation transfer spectroscopy and laser ...

Locking of a laser frequency to an atomic or molecular resonance line is a key technique in applications of laser spectroscopy and atomic metrology. Modulation transfer spectroscopy (MTS) provides an accurate and stable laser locking method which has been widely used. Normally, the frequency of the MTS signal would drift due to Zeeman shift of the atomic levels and rigorous shielding of stray ...

Laser frequency stabilization by combining modulation ...

We present a hybrid laser frequency stabilization method combining modulation transfer spectroscopy (MTS) and frequency modulation spectroscopy (FMS) for the cesium D2 transition. In a typical pump-probe setup, the error signal is a combination of the DC-coupled MTS error signal and the AC-coupled FMS error signal.

We report on an optical frequency standard at λ = 612 nm, which takes the form of a He-Ne laser stabilized with respect to molecular iodine by means of frequency modulation spectroscopy. The measured frequency stability was σ0(τ) = 8,7 × 10-13 τ-1/2 for sampling times (τ) between 10-3 s and 103 s, and the estimated reproducibility was 1,2 kHz. Spectroscopy of the R(47) 9-2 transition was ...

US4590597A - Modulation transfer spectroscopy for stabilizing ...

Stabilization is based on the detection of modulation transferred onto a previously unmodulated probe beam by the non-linear interactions of the absorbing gas located in a cell which is subject to a counter-running, frequency-modulated saturation beam. Alternatively, the further modulation of the saturation beam can be detected.

This combines the long-term stability of the former with the high signal-to-noise ratio of the latter. In addition, we enhance the long-term frequency stability with laser intensity stabilization. By measuring the frequency difference between two independent hybrid spectroscopies, we investigate the short-and long-term stability.
