Design and Analysis the Fiber Laser Weapon System FLWS

The laser weapon system has many advantages over traditional projectile weapons such as bullets and rockets. This paper presents a new design of fiber laser weapon system FLWS. Design of FLWS requires the expansion of application fields as diverse as quantum mechanics and aerodynamics. FLWS has been designed for destruction any target, for example a spy aircrafts and missiles. FLWS consist of 16-fiber individual of an ytterbium fiber laser with optical core radius of ~ 20μm, each fiber emitting a single-mode of CW power about 10 kW with initial beam spot size (50mm) and have a beam director radius of ~20cm It has been demonstrated by simulations, the power needed to destroy any target made of steel (missile or aircraft) approximately about 73500watts.This represents a threshold power of FLWS, which must be overcome to destroy the target. The threshold power varies considerably depending on many factors as the range of FLWS (RFLWS), attenuation of atmosphere μ and reflectivity of skin target. The quality beam of threshold power is inversely proportional to M2 factor N-fiber and RFLWS. Keywords: Laser Weapon, Fiber laser, M2 factor, Attenuation of atmosphere μ, Beam divergence

Analysis and Study of the Effect of Atmospheric Turbulence on Laser weapon in Iraq

One of the most important challenges facing the development of laser weapons is represented by the attenuation of the laser beam as it passed through the layers of atmosphere.This paper presents a theoretical study to simulate the effect of turbulence attenuation and calculates the decrease of laser power in Iraq. The refractive index structure C_n^2 is very important parameter to measure the strength of the atmospheric turbulence, which is affected by microclimate conditions, propagation path, season and time in the day. The results of measurements and predictions are based on the Kolmogorov turbulence theory. It was demonstrated by simulations that the laser weapons in Iraq were severely affected due to the large change in temperatures, the limited effective range of laser weapon to a few kilometers as a result of high attenuation and the middle of stratosphere considered as a homogeneous and a suitable area for the work of laser weapons, so be a favorite area of fighter aircraft
