ABSTRACT:
A calibration apparatus is disclosed for measuring the properties of a laser beam. The apparatus includes a photoreactive element having a composition which reacts with laser radiation in a manner proportional to the intensity or intensity profile of the laser beam and an alignment means for disposing the photoreactive element in the path of a laser beam, such that the beam can be activate to impinge upon the photoreactive element and the properties of the beam are recorded by changes in the state of the calibration element. The calibration element may also be used to provide corrective feedback for modifying or controlling the properties of the laser beam.
