What does 'interlock' refer to in the context of laser safety?

In the context of laser safety, 'interlock' refers to a feature designed to prevent access to laser beams during operation. This safety mechanism ensures that when a laser is active, certain areas or doors are secured, effectively reducing the risk of accidental exposure to the laser beam. By implementing interlocks, operators can maintain a safer working environment where access to hazardous areas is restricted unless the laser is completely shut down or deactivated.

The focus of this safety feature is on the prevention of accidental exposure, making it a crucial element in the design of laser facilities and equipment. This kind of system is particularly important in environments where powerful lasers are operated, as it helps minimize the chances of injury to personnel who may inadvertently enter the area where the laser is active.
