ABSTRACT In the contemporary scientific field, in the Middle Eastern war, the laser weapon became a subject of strategic importance used in the field of defense. Our study came to complete the theory and experience of using these weapons in the interaction with metals. Based on the experiences carried out strategically in Romania with lasers of different types, we proceeded to the theoretical evaluation of the laser light field based on the system of Maxwell's equations. The electric field was mathematically obtained with a value of 1,05×〖10〗^4 V/m which has the role of producing the light effects and estimating the intensity of the incident laser light that attacks the target and irradiates it. A value was obtained on a 10 mm thick Hardox 400 target that protects electronic equipment equal to 4,5x106 W/cm2. Another important quantity in laser attack is the energy supplied to the target to create the piercing bore, where a value of 3 MJ was obtained for a laser spot with a focal diameter of 0.38 mm. Laser radiation intensity and energy are the two important quantities that have destructive effects on metal targets (drones, missiles). |
