由于超轻轴子凝聚体与电磁场的耦合，将其激光化为光子对背景等离子体的存在很敏感。这种情况特别适用于恒星质量黑洞周围的超辐射轴子凝聚，因为轴子质量可以在周围介质等离子体频率的几个数量级内。本文讨论了黑洞周围等离子体的性质，分析了等离子体对等离子体频率量级质量的均匀轴子凝聚体激光的影响。
Lasing of ultralight axion condensate into photons can be sensitive to the presence of a background plasma owing to its coupling to electromagnetism. Such a scenario is particularly relevant for superradiant axion condensate around stellar mass black holes since the axion mass can be within a few orders of magnitude of the plasma frequency of the surrounding medium. In this paper I discuss the properties of the plasma around a black hole and analyze its effects on the lasing of a uniform axion condensate of mass of the order of the plasma frequency.
