After that the industry will have to move on to nonoptical techniques, such as electron beams or even X rays, which have wavelengths less than a nanometer, one thousandth of a micron.

After that the industry will have to move on to nonoptical techniques, such as electron beams or even X rays, which have wavelengths less than 1 nanometer, or one-thousandth of a micron.

The beams were injected at 450 billion electron volts, only a fraction of the energy that scientists will aim for when they attempt to collide two particle beams.

The high average power infrared Free Electron Laser (FEL) provides intense beams of laser light that can be tuned to atmosphere-penetrating wavelengths.
