We present a compact, monolithic optical reference for the frequency stabilized laser of future inter-satellite laser interferometer missions. A prototype based on the integration of a high-finesse cavity and associate optics has been designed to be space compatible while maintaining sufficient stability. The prototype has then been developed with a space-qualified bonding technique, and an in situ multi-degree-of-freedom alignment method. The performances of the optical reference have been studied by beat note analysis with another frequency stabilized laser, and the preliminary results are in agreement with the potential requirements of future space missions.
我们为未来的星间激光干涉仪任务中的频率稳定激光器展示了一种紧凑的单片光学参考装置。基于高精细度腔和相关光学器件集成的原型已被设计成与太空兼容，同时保持足够的稳定性。然后，该原型采用了符合太空标准的键合技术和原位多自由度对准方法进行开发。通过与另一台频率稳定激光器进行拍频分析研究了该光学参考装置的性能，初步结果符合未来太空任务的潜在要求。
