Abstract

Classification of laser products according to the Federal Laser Product Performance Standard depends, in part, on the measurement of laser radiation. The parameters of interest, namely power, energy, irradiance, radiant exposure, and radiance, are discussed. The accessible emission limits for each class of laser product are presented for selected products The measurement requirements of the Laser Product Performance Standard are discussed, namely, power and energy measured in an 80 mm aperture, irradiance and radiant exposure within a 7 mm aperture, and radiance and integrated radiance within a 7 mm aperture and 10-5 steradians. The Bureau of Radiological Health's instrumentation kit is discussed along with a brief description of some of the instruments and their use. Finally, a discussion of instrument calibration procedures and recordkeeping is presented.
