There are two types of micro lasers: fiber lasers or laser cavities and single-tube semiconductor lasers. The synthesis is carried out in three steps: the first step is to integrate many small fiber lasers into a linear array in parallel to form a “bar”; the second step is to integrate many bars in the horizontal direction into a “area array”; the third step, Integrate many area arrays vertically into a “stacked array”. In this way, from point to line, from line to surface, from surface to stack, the weak lasers emitted by many small fiber lasers are integrated into a strong laser.
In addition, for single-tube semiconductor lasers, the beam is converged into the optical fiber and then output. The second key technology is to combine multiple beams. The so-called beam combining means combining multiple stronger green laser pointer beams into a laser beam with greater energy and higher power. The typical beam combining method is to control the beam to overlap and overlap at a longer distance, which is the so-called “spatial beam combining”. Some laser weapon systems in the United States and Germany are constructed based on this principle.
The other is spectral beam combining, which is achieved by precisely adjusting and combining multiple laser beams of different wavelengths. In actual combat, the “iron beam” laser weapon system emits two strong lasers from two launch vehicles and superimposes them on the target aiming point to accumulate greater laser energy to achieve the goal of effectively killing the target. Since 2014, conflicts have continued in the Gaza region, and Israel has been hit by a large number of rockets. This shows that Israel’s opponents have been able to take advantage of the inherent technical weaknesses of the “Patriot-3” system and the “Iron Dome” system.
Saturation air strikes are carried out by launching low-cost weapons such as drones, cruise missiles, and rockets. When the “Iron Dome” system is difficult to complete the interception mission, the “Iron Beam” high-energy laser weapon with its compact and efficient, low operational cost, and easy-to-guarante strong laser effect, in one fell swoop to reverse the Israeli army’s tactical difficulty in intercepting and strategic The double situation of passive beating. In future operations, missile anti-missile and laser pointer anti-missile means will be used in conjunction with complementary advantages.
In severe weather conditions or when non-linear killing is required, the “Iron Dome” air defense missile intercepts; in good weather conditions or when straight shooting is possible, it is handed over to laser weapons to effectively combat drones or precision Volleys of guided munitions and threats of mass attacks.
