    "abstract": "A theoretical description in terms of the coherence propagation is given for\nself-focussing. The concept of coherence length is defined in terms of free,\nself-focussing propagation giving results in accordance with well known\nexperimental criteria for the laser. Extension of the method is given for an\nAtom Laser showing good results in agreement with recents numerical results of\nTrippenbach et. al.: J. Phys. B:At. Mol. Opt. Phys. 33, 47-54 (2000).",
