An atomic laser based on neon atoms and pumped by a soft-X-ray (that is, a photon energy of less than one kiloelectronvolt) free-electron laser has been achieved at a wavelength of 14 nanometres. Here, we use a copper target and report a hard-X-ray inner-shell atomic laser operating at a wavelength of 1.5 angstroems. Ã¥ngstrÃ¶ms
Japan fires world's most powerful laser to produce energy equal to 1,000 times the planet's power consumption. 1  LFEX device produced 2-petawatts (2 quadrillion-watts) of energy. 2  The energy used for the laser beam itself would only be powerful enough to run a microwave for around two seconds, the Osaka researchers claim.
