In the atmosphere, after lightning, precipitation is formed and heavy rainfall occurs. This is a well-known process. This natural lighting phenomenon has been practically demonstrated in the laboratory cloud chamber, A laser beam has to be shot into the cloud region of the atmosphere to create high temperature. This high temperature will break the bonds of atmospheric N2 and O2 and produce N and O which will be in excited state (N*, O*). These excited N* and O* are very unstable. They immediately fall to the ground state through endothermic reactions. These endothermic reactions absorb heat from the cloud region. As a result, temperature of the cloud region falls, condensation takes place, form rain drops, act as natural seeds are created and it rains. Its use as rain drain by Laser system from ground for Green environment. “Laser photons photo-dissociate atmospheric compounds N2 and O2 and form ozone (O3) and nitrogen molecules (NO). Increase of O3 and NO concentration after lightning has also been experimentally observed. That this lightning phenomenon created through artificial lightning by laser system can produce rain in the atmosphere has been practically proved as “Laser-induced water condensation in air”. Scientists have succeeded in obtaining raindrops from an altitude of 45 to 75m of the atmosphere by terawatt mobile laser. IRRA Scientist Group propose laser system of specification: 1012watt, 800nm, 500mJ, 120fs and 10Hz for this research project. The results could be of immense benefit to human being.
