This technical report gives information on the physics relating to the dangers posed by laser products. It complements, but does not replace, the information in IEC 60825-1 by explaining the underlying principles, so that the user may correctly interpret its requirements.The application of this technical report is limited to laser products with finite accessible emissions of laser radiation.
