High power deep ultraviolet laser source

WebThe specific combination of the rare gas and the halogen determines the output wavelength of the laser. The excimer laser is the best known practical source of intense deep-UV radiation. The short wavelength UV energy from excimer lasers causes high levels of electronic excitation in irradiated materials leading to bond breaking and photoablation. WebMar 1, 2024 · In a laser-driven EUV source, laser energy, usually in the form of rapid, ultrashort pulses, is focused on a solid, liquid or gaseous target. Absorption of high laser peak powers results in the formation of a dense, hot plasma, much like those found in certain highly energetic stellar sources.
