论文摘要
我们提出了一种基于固态的超级激光，几乎对空腔镜振动不敏感。因此，它可以与最频率稳定的本地振荡器竞争。使用较长的连贯性时间和稀土离子（Reis）掺杂固体的较大光密度来找到一个制度，以证明稳态激光发射的线宽小于原子衰减速率。讨论了实验参数，并根据平均场理论计算腔内光子数和激光线宽。提出了测量绝对激光线宽的程序。
We propose a solid-state based superradiance laser which is almost insensitive to the cavity mirror vibration. Therefore, it can compete with the best frequency-stable local oscillators. The long coherence time and the large optical density of rare-earth-ions (REIs) doped solids are employed to find a regime to demonstrate a steady-state laser emission with linewidth smaller than the atomic decay rate. The experimental parameters are discussed and intracavity photon number and laser linewidth are calculated based on the mean-field theory. A procedure for measuring absolute laser linewidth is proposed.
