Laser using narrow band intercombination line of Calcium — Hannes Winter, •Torben Laske, and Andreas Hemmerich — Institut für Laserphysik, Hamburg
We present our setup for realizing a superradiant laser [1] similar to the proposal to [2] using the narrow Calcium intercombination line 41S0 ↔ 43P1 as the laser transition. Such a laser operates in the bad-cavity regime, in which the coherence is not stored in the intra cavity light field but in the gain medium. The ultracold Calcium atoms are trapped in the Lamb-Dicke regime by a one dimensional intra cavity lattice to control the Doppler effect. Unlike conventional lasers, the expected frequency stability of this light source is not limited by mechanical fluctuations of the cavity length, which yields important implications for applications like time metrology.
