Abstract
In the operation of analytical devices, and particularly laser induced breakdown spectroscopy (LIBS) devices, a number of advantages may be obtained by the use of complementary safety mechanisms, such as those that govern the operation or firing of a laser. Such complementary safety mechanisms, compared to the individual safety mechanisms acting alone, prevent operation of the laser under a greater number of unsafe circumstances (even if one or more detected conditions are safe, based on not activating the associated safety mechanism) and permits operation under a greater number of safe circumstances (even if one or more detected conditions are unsafe, based on activating the associated safety mechanism).
