    "abstract": "We derive and apply an optical Bloch equation (OBE) model for describing\ncollisions of ground and excited laser cooled alkali atoms in the presence of\nnear-resonant light. Typically these collisions lead to loss of atoms from\ntraps. We compare the results obtained with a quantum mechanical complex\npotential treatment, semiclassical Landau-Zener models with decay, and a\nquantum time-dependent Monte-Carlo wave packet (MCWP) calculation. We formulate\nthe OBE method in both adiabatic and diabatic representations. We calculate the\nlaser intensity dependence of collision probabilities and find that the\nadiabatic OBE results agree quantitatively with those of the MCWP calculation,\nand qualitatively with the semiclassical Landau-Zener model with delayed decay,\nbut that the complex potential method or the traditional Landau-Zener model\nfail in the saturation limit.",
