Abstract
The laser lawn cutting system of the present invention consists of an array or grid of laser heads distributed across a lawn. The laser heads may be permanently fixed above the surface of the lawn, or preferably mounted underneath the surface of the lawn and designed to pop up at the time of cutting. If mounted underneath the surface of the lawn, solenoids may be used to move the laser heads above the surface. Other mechanical devices could also be used to cause the laser heads to move above the surface of the lawn. Preferably, the laser heads will be distributed across the lawn in a grid or matrix, such that the laser light generated by the rotating laser head sweeps across the lawn in overlapping arcs to cut the vegetation. The system may also be used to melt snow or kill insects.
