A preliminary prototype of laser frequency stabilization for spaceborne interferometry missions
2016
A preliminary prototype of spaceborne laser frequency stabilization system for inter-satellite laser ranging missions has been constructed and demonstrated on ground. The system is based on hydroxide-catalysis bonding and fiber optics. The laser frequency control is driven by an in-house-designed digital controller featuring self-analysis and auto-locking functions. Laser frequency noise less than 30 Hz/Hz1/2 from 0.7 Hz to 10 Hz has been measured by beat note analysis. The laser stabilization system has been tested on a laser interferometer test bed. Preliminary experimental results are reported in this paper.
