Self-distributed feedback lasing in a system of cold atoms / B.W.J. McNeil, G.R.M. Robb, R. Bonifacio, N. Piovella. - In: EUROPHYSICS LETTERS. - ISSN 0295-5075. - 49:3(2000), pp. 316-321.
Abstract:
We present a semiclassical analysis of lasing with an injected signal in a system of cold two-level atoms where the effects of atomic recoil are included self-consistently. This analysis predicts that the atoms may bunch under the effects of dipole forces to produce a density grating. This grating produces distributed feedback which can induce lasing action even when the gain of the atomic medium is less than the cavity losses.
