The study of the Resultant of Attenuation in laser Radiance by Humidity Effecting on using two Types of water

Abstract

This research sheds the light on the effects of one weather factors  the humidity which are got from vaporing two rinds of water Tigress water and distilled water so they affect laser beams transmittance and change of  humidity ranges. The laser of continuous CO2 with wave length 10.6 µm with power reads 0.8 mw  and the laser of He-Ne laser with wave length of 632 nm with power reads 2.04 mw The beams of  laser in the cell attenuation  and   measuring laser  by using power sensor 's then using  the effect factors after going on 2m. Then transmittance decrease with high humidity . The relation between transmittance ranges for beams of laser and humidity depend on spectrum of water vapor absorption, wave light of lasers, powers of. Therefore the effect of humidity that is got by vaporing water that this process becomes more effective on, the transmittance of laser than using other kinds of water. The reason is that, rivers water contains many melted elements which may vapor through increasing temperature to boiling and eventually it affects transmittance.
