Description

Laser phase-noise (PM) to detected intensity-noise (AM) conversion is fundamental to the field/matter interaction: it cannot be avoided, only mitigated. It occurs when laser light passes through a resonant atomic vapor in atomic clocks, magnetometers, and rf-sensors, and it occurs when laser-induced-fluorescence is detected from an atomic or molecular beam. More specifically, it is a tall-pole noise source in many next-generation vapor-cell atomic clocks. In this presentation the origin of PM-to-AM conversion will briefly be reviewed with attention to recent experiments aimed at better understanding the phenomenon and developing mitigation strategies.
