The invention provides a laser system and method for administering multiple beams of laser energy in tissue treatment applications. The system administers the beams simultaneously in a distribution pattern of spatially separated overlapping and non-overlapping regions on a tissue. The simultaneous administration and distribution pattern permit the beams to propagate within a tissue without producing the light scattering effects that characterize the sequential application of multiple laser beams to a tissue. The laser system can comprise tissue cooling and laser cooling components.
