The report presents information obtained from initial experiments involving the use of a laser to degrade and deteriorate hard rock samples. The work is being done within the context of a continuing search for more efficient means of excavation and tunnelling in hard rock. The techniques discussed herein should be considered in the context of making hard rock more easily removed by reducing its strength. The laser appears to have an unusual potential for this application. (Author)
