How does any of this stuff really work? It seems as close to magic as I can possibly imagine, the idea that the laser source alone for EUV lithography fires a laser twice at single tiny droplets of falling tin, once to turn the droplet to tin plasma and again to generate the right wavelength of light, all in a fraction of a second, and this happens at up to 50,000 times per second. Seems mad to me...
