Abstract

The present invention provides a method and apparatus for cutting wood or other materials by separating the material along a line of controlled failure through the application of mechanical force in combination with laser light to break molecular bonds holding the material together along the line of controlled failure. A preferred embodiment of the cutting apparatus is a generally broad wedge-shaped blade having planar lower and upper surfaces which converge toward each other to terminate along a leading edge. The blade is generally hollow with a cavity for passing optical fibers carrying laser light to a transparent window attached to the leading edge of the blade. Laser light passes through the window and is directed to a line of controlled failure in the material being cut to break the molecular bonds and locally weaken the material.
