Abstract
A method and apparatus for concentrating the heat energy of a laser beam by directing the laser beam to an optical device, such as a planar mirror, located at a first focal point of a reflector having a curved surface approximating that of an ellipsoid. The optical device redirects the laser beam to the curved surface of the reflector which reflects and focusses it to a second focal point of the reflector. The optical device is driven to cause the laser beam to successively scan different portions of the curved surface of the reflector while the latter surface reflects the laser beam substantially to the second focal point where the object to be heated is located.
