Laser systems of classes 3B and 4 must be constructed in accordance with the German Ordinance on the Protection of Employees Against Hazards caused by Artificial Optical Radiation (OStrV) in such a way that no hazardous laser radiation can penetrate through to the outside. Electronic interlocks on the laser that prevent laser emission within an open laser environment (such as an open door or flap) represent one option for ensuring this protection is provided.
