Abstract: 1.IN A METHOD OF APPLYING AN ANTI-REFLECTIVE COATING WHEREIN THE IMPROVEMENT COMPRISES THE STEPS OF COATING AN END SURFACE OF A SEMICONDUCTOR LASER WITH AN ANTI-REFLECTIVE MATERIAL IN A MANNER SO AS TO PROGRESSIVELY INCREASE THE THICKNESS OF THE LAYER OF THE MATERIAL,

MEASURING THE RADIANT ENERGY OUTPUT OF THE LASER DURING THE COATING AS THE THICKNESS OF THE COATING UNCREASE, AND STOPPING THE COATING WHEN A DESIRED OUTPUT IS ACHIEVED.
