Technical description

- Commodity name: Doppler elimination saturation absorption frequency stabilization module
The anti-Doppler saturation absorption frequency stabilization module consists of optical circuit, detection circuit and frequency stabilization circuit. All three modules can be customized and can be purchased separately.

Doppler elimination saturation absorption frequency stabilization module, composed of three parts:

First, anti-Doppler saturation absorption optical path

Composed of PBS, λ/4 wave plate, mirror, photodetector, etc., the light path is compact and stable, easy to adjust.

Second, anti-Doppler saturation absorption detection circuit

The signal obtained by the photodetector is processed (proportional amplification, error, etc.), and the Doppler attenuation saturation absorption spectrum is obtained.

Three, PID frequency stabilization circuit

The discriminating curve is obtained from the saturation absorption spectrum and fed back to the laser for laser frequency stabilization.
