Optimization strategies for modulation transfer spectroscopy applied to laser stabilization. [PDF]

Optics Express, 2018
We present a general analysis for determining the optimal modulation parameters for the modulation transfer spectroscopy scheme. The results are universally valid and can be applied to spectroscopy of any atomic species requiring only the knowledge of ...

Carrier frequency modulation of an acousto-optic modulator for laser stabilization. [PDF]

Optics Express, 2017
The stabilization of lasers to absolute frequency references is a fundamental requirement in several areas of atomic, molecular and optical physics. A range of techniques are available to produce a suitable reference onto which one can 'lock' the laser ...

Spurious Tone Reduction and Signal Stabilization of Optoelectronic Oscillators by Low-Frequency RF Signal Modulation

Photonics, 2022
In this study, the oscillation signal stabilization and spurious tone suppression of a directly modulated optoelectronic oscillator (DM-OEO) are simultaneously achieved by modulating a laser with a low-frequency radio frequency (RF) signal.

Simple laser stabilization to the strontium ⁸⁸Sr transition at 707 nm. [PDF]

Review of Scientific Instruments, 2015
We describe frequency stabilization of a laser at 707 nm wavelength using FM spectroscopy in a hollow cathode lamp. The laser is stabilized to the (88)Sr metastable (3)P2 to (3)S1 optical transition. The stabilized laser is utilized for laser-cooling and
