Design and Analysis the Fiber Laser Weapon System FLWS

Abstract

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 (R_FLWS), attenuation of atmosphere μ and reflectivity of skin target. The quality beam of threshold power is inversely proportional to M² factor N-fiber and R_FLWS.
