Can lasers ionize air
WebJun 28, 2012 · The pathway takes the form of an electrically conductive plasma channel that is formed when a laser beam of enough intensity (a 50 billion watt pulse lasting two-trillionths of a second will do)... WebDec 5, 2024 · 1 Answer Sorted by: 0 With a 1064 nm (i.e. infrared) laser you cannot ionize air molecules. The ionization energy of oxygen and nitrogen molecules is around 14 eV. Therefore you need photons with an energy of at least 14 eV, i.e. a wavelength shorter than 80 nm. This is already ultraviolet light.
