We have investigated formation of structures of Rydberg atoms excited from a disordered gas of ultracold atoms, using rate equations (REs) for two-photon Rydberg excitation in a single atom without eliminating the intermediate state. We have explored the validity range of these REs and defined a simple measure to determine, whether our model is applicable for a given set of laser parameters. We have applied these REs in Monte Carlo simulations of ultracold gases, for different laser beam profiles, and compared these simulations to experimental observations and find a general agreement.
