摘要
具有超高频率稳定度的连续波激光是目前一系列空间引力波探测计划中所采用的光源,但自由运转的激光难以满足空间引力波探测对激光频率噪声的控制要求,需要通过频率预稳对激光的频率噪声特别是其中的低频成分进行有效抑制.介绍星载稳频激光的基本构成和研究现状.以目前正在研制的星载稳频激光为例分析目前稳频激光的发展趋势.随着空间稳频激光性能指标和环境适应性的不断提高,这类激光将在空间相干光通信和卫星重力测量等空间科学应用中发挥重要作用.
Abstract
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.
