دراسة العوامل المؤثرة على إنتقال أشعة الليزر ذات أطوال موجية (670، 976 و 1300)‎ نانومتر في منظومة الاتصالات الليزرية الحرة

الملخص EN

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.
