The objective of this proposal is twofold. 1. Based upon our recent successful demonstration of pulsed superradiant lasing using the 1S0 -> 3P1-intercombination transition of calcium at 657 nm with 380 Hz natural line width, we plan to demonstrate the realization of continuous operation, as an important step towards application of this new laser concept for time metrology. 2. We furthermore plan to demonstrate (pulsed and continuous) superradiant lasing using the far more narrow 1S0 -> 3P0-intercombination transition, whose line width can be tuned by a static magnetic field of a few Gauss in the sub-Hertz range.

这项建议的目的是双重的。1. 基于我们最近成功演示的脉冲超辐射激光，利用钙的1S0 -> 3p1 -互组合跃迁在657nm， 380 Hz自然线宽，我们计划演示实现连续操作，作为将这种新的激光概念应用于时间计量的重要一步。2. 我们进一步计划演示（脉冲和连续）超辐射激光，使用更窄的1so0 -> - 3p0 -互组合跃迁，其线宽可以通过亚赫兹范围内几高斯的静态磁场来调谐。
