Claim 1
Independent Claim
188 words
A METHOD OF FORMING RELATIVELY SMALL HOLES IN A MATERIAL WHEREIN A PLUSED BEAM OF COHERENT LIGHT PRODUCED BY A SASER IS FOCUSED ON THE MATERIAL TO BE PIERCED BY MEANS OF A REFLECTING OBJECTIVE LENS COMPRISING THE STEPS OF POSITIONING A MATERIA TO BE PIERECED AT A SELECTED POINT RELATIVE TO THE FOCAL POINT OF REFLECTING OBJECTIVE LENS, CONTROLLING THE AMOUNT OF ELECTRICAL ENERGY TO BE UNLIZED BY A LASER DEVICE IN GENERATING A PLUSED LASER BEAM WHEREBY THE SIZE OF THE HOLE PRODUCED IN THE MATERIAL BY THE LASER BEAM VARIES WITH THE AMOUNT OF ELECTRICAL ENERGY, ADJUSTING THE CROSS SECSTION OF THE LASER BEAM TO BE GENERATED BY POSITIONING A LIMITING APERATURE INTERMEDIATE THE LASER DEVICE AND THE REFLECTING OBJECTIVE LENS AND ALONG THE OPTICAL AXIS OF THE LASER BEAM, AND UTILIZING THE CONTROLLED AMOUNT OF ELECTRICAL ENERGY TO GENERATE A PULSED LASER BEAM WHICH PASSES THROUGH THE LIMITING APERTURE AND IS FOCUSED ON THE MATERIAL TO BE PIERCED BY MEANS OF THE REFLECTING OBJECTIVE LENS WHEREBY THE HIGHLY CONCENTRATED ENERGY OF THE FOCUSED PLUSED LASER BEAM PIERCES A RELATIVELY SMALL HOLE THROUGH THE MATERIAL.
