摘要
我们展示了为国际空间站（ISS）上众多量子技术实验设计的激光系统，特别是双物种87Rb和41K玻色-爱因斯坦凝聚体。展示了飞行模型（FM）和基于商业现货（COTS）的模型，两者在功能上均满足BECCAL要求，但在尺寸、重量和功耗（SWaP）及环境要求方面存在差异。讨论了两者的能力并进行了比较。BECCAL的飞行模型采用专为开发和资质的定制组件，构建紧凑且稳健的系统，适合在ISS上进行长期远程操作。该系统基于ECDL-MOPA激光器和采用Zerodur制造的自由空间光台，以及商业光纤组件。而COTS-based系统则完全采用商业部件，构建功能等效的实验室操作系统，无需严格的SWaP和环境限制。
