WebAnswer (1 of 8): Yes, a laser can ionize a gas, but most lasers today don't actually do it. Two ways it can: a) Its wavelength is UVc or shorter. Its photon energy is higher than the ionization energy of some of the atoms or molecules in the gas. It doesn't even matter if a far-UV laser is puls... WebIonizing radiation is the cause of blue glow surrounding sufficient quantities of strongly radioactive materials in air, e.g. some radioisotope specimens (e.g. radium or polonium), …

WebThe bright light you see is the air combusting under the rim of the craft. The basic idea behind light propulsion is the use of ground-based lasers to heat air to the point that it explodes, propelling the spacecraft forward. If it … 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)... church suffering church triumphant

WebJan 11, 2024 · Yes it is possible. You need a strong laser though, with peak powers in the terawatt range. The key thing for that to actually work over distances longer than a few mm or cm is an effect called filamentation. This is a kind of self-guiding property of air at very high light intensities (starting at TW). WebMay 26, 2024 · A multi kW powered CO2 laser can easily strip an atom of many electrons. Such lasers are used to generate extreme ultraviolet (EUV) light for computer chip manufacturing. ... , in which a long-wavelength laser is used to ionize air at its focus. This is mostly an avalanche phenomenon (see this answer for more details) ... 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. dexflex white rosita sandals
