WebA laser emits a laser beam into the air. The laser beam rapidly heats and ionizes surrounding gases to form plasma. The plasma forms an electrically conductive plasma channel. Because a laser-induced plasma channel relies on ionization, gas must exist between the electrolaser weapon and its target. WebProcesses. When energy is deposited to air, the air molecules become excited. As air is composed primarily of nitrogen and oxygen, excited N 2 and O 2 molecules are produced. These can react with other molecules, forming mainly ozone and nitrogen(II) oxide. Water vapor, when present, may also play a role; its presence is characterized by the hydrogen … iowa therapists
