Can lasers ionize air

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. WebElectrolaser. An electrolaser is a type of electroshock weapon that is also a directed-energy weapon. It uses lasers to form an electrically conductive laser-induced plasma channel …
