  • Method and apparatus for measuring the relative intensity of the beams emanating from a single laser
    Patent number: 4261662
    Abstract: The laser beam to be measured is focussed onto a photographic film to rec the beam pattern. A second laser beam is then used to measure the displacement of the side lobes from the main beam. An apertured metal plate is then substituted for the film and, by the use of a beam deflector and a calorimeter, the intensity of the main beam alone is measured. Using the beam displacement data previously recorded, the metal plate is then moved to co-incide with one of the side lobes and the intensity of the side lobe recorded. This procedure is repeated for all remaining side lobes.
