دراسة العوامل المؤثرة على انتقال اشعة الليزر ذات أطوال موجية ( 670, 976 و1300) نانومتر في منظومة الاتصالات الليزرية الحرة

Abstract

This work focused on the effects a Relative Humidity and concentration of dust of Atmospheric different cities of Babylon for the laser beam have different wavelengths ( 670 , 976 and 1300 nm) . The results show the laser beam have wavelength 1300nm is little effected in this parameters and the atmospheric of Al-Mussaib is the best for propagation laser beam at minimum attenuation
