Selfsynchronization and dissipation-induced threshold in collective atomic recoil lasing
C. von Cube, S. Slama, D. Kruse +5
Networks of globally coupled oscillators exhibit phase transitions from incoherent to coherent states. Atoms interacting with the counterpropagating modes of a unidirectionally pum…
Observation of Lasing Mediated by Collective Atomic Recoil
D. Kruse, C. von Cube, C. Zimmermann +1
We observe the buildup of a frequency-shifted reverse light field in a unidirectionally pumped high- optical ring cavity serving as a dipole trap for cold atoms. This effect is…
Cold atoms in a high-Q ring-cavity
D. Kruse, M. Ruder, J. Benhelm +6
We report the confinement of large clouds of ultra-cold 85-Rb atoms in a standing-wave dipole trap formed by the two counter-propagating modes of a high-Q ring-cavity. Studying the…
Optical Lattice in a High Finesse Ring Resonator
B. Nagorny, Th. Elsaesser, H. Richter +4
An optical lattice with rubidium atoms () is formed inside a ring resonator with a finesse of and a large mode volume of 1.3 . We typically trap se…
