Continuously emitting superradiant laser utilizing intercombination lines of calcium

• Applicant: Professor Dr. Andreas Hemmerich
• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: from 2014 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 253346256

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.
