Pulse delay time statistics in a superradiant laser with calcium atoms
Torben Laske, Hannes Winter, Andreas Hemmerich
Cold samples of calcium atoms are prepared in the metastable P state inside an optical cavity resonant with the narrow band (375 Hz) SP$_{1…
Inelastic collisions of optically trapped metastable calcium atoms
Purbasha Halder, Hannes Winter, Andreas Hemmerich
We study binary collisions of metastable calcium atoms (Ca) in an optical dipole trap. Collisions between P-atoms and between P and S-ato…
Magnetic Trapping of Metastable Calcium Atoms
Dirk P. Hansen, Janis R. Mohr, Andreas Hemmerich
Metastable calcium atoms, produced in a magneto-optic trap (MOT) operating within the singlet system, are continuously loaded into a magnetic trap formed by the magnetic quadrupole…
Optimizing the production of metastable calcium atoms in a magneto-optical trap
Jan Gruenert, Andreas Hemmerich
We investigate the production of long lived metastable (3P2, n=4) calcium atoms in a magneto-optical trap operating on the 1S0 to 1P1 transition at 423 nm. For excited 1P1-atoms a…
Ultracold Metastable Calcium Ensembles, a Medium for Matter Wave Amplification ?
J. Gruenert, G. Quehl, V. Elman +1
We propose an experimental implementation of matter wave amplification by optical pumping (MAO) with metastable calcium atoms. First experimental results indicate that pumping rate…
