我们提出了一种基于热原子束穿过光学腔的新型超辐射激光器。我们证明了理论最小线宽和最大功率与最好的超相干时钟激光器竞争。此外，我们的系统在连续波模式下自然运行，这对于超辐射激光器来说是难以捉摸的。与现有的超相干激光器不同，我们的设计简单而坚固。这使得它成为第一个广泛使用的超相干激光器的候选者，也是第一个在具有挑战性的环境中实现超相干激光器的追捧应用的候选者。
We propose a new type of superradiant laser based on a hot atomic beam traversing an optical cavity. We show that the theoretical minimum linewidth and maximum power are competitive with the best ultracoherent clock lasers. Also, our system operates naturally in continuous wave mode, which has been elusive for superradiant lasers so far. Unlike existing ultracoherent lasers, our design is simple and rugged. This makes it a candidate for the first widely accessible ultracoherent laser, as well as the first to realize sought-after applications of ultracoherent lasers in challenging environments.
