Laser percussion

Keywords— Laser Percussion, CW CO2 Laser, Biological Tissue, Laser-induced Sound, Microphone. 

Part of an explosive train which initiates the - detonation of high explosives, especially of insensitive ones. It may itself be triggert by a seperate -> primer of primary explosives or an integrated primer. Detonators are classified by the method of initiation percussion, stab, electrical impulse, or flash. Laser initiation is also used. Depending on the application detornators can include a delay mechanism. Explosive charge placed in certain equipment and set to destroy the equipment under certain conditions (- Initiator). 

Laser Beam Machining, Fig. 5 Process approaches for single pulse, percussion, and trepanning drilling (a-c) as well as machining (d) with focused laser beams... 

Thermal batteries are activated by applying an external signal to an initiation device that is incorporated in the battery. There are four generally used methods of activation electric signal to an electric igniter mechanical impulse to a percussion primer mechanical shock to an inertial activator and optical energy (laser) signal to a pyrotechnic material.
