Development of Frequency-Stabilized Lasers in Space-Based Gravitational Wave Detection
Continuous wave lasers with ultra-high frequency stability are adopted as light sources in many space missions for gravitational wave detection.Free-running lasers are unable to meet the requirements for laser frequency noise control in space-based gravitational wave detectors,and it is necessary to adopt a frequency pre-stabilization stage to effectively suppress the frequency noise of the laser,especially those low-frequency noise components.The basic composition of spaceborne frequency-stabilized lasers is outlined,and their research status are introduced.Taking a spaceborne frequency-stabilized laser that is currently under development as an example,the development trend of spaceborne frequency-stabilized lasers is analyzed.With the continuous improvement of their performance and environmental adaptability,spaceborne frequency-stabilized lasers will play an important role in space applications such as coherent optical communication and satellite gravity measurement.
