ALEXANDRIA, Va., June 16 -- United States Patent no. 12,660,255, issued on June 16, was assigned to ColdQuanta Inc. (Boulder, Colo.).
"Pulsed-laser modification of quantum-particle cells" was invented by Steven Michael Hughes (Louisville, Colo.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A pulsed-laser applies short (e.g., less than 10 pico-seconds) pulses to modify quantum particle (e.g., alkali-metal and alkaline-earth-metal atoms) ultra-high vacuum (UHV) cells to bond, ablate, and/or chemically modify vacuum-facing surfaces of the cell. The pulses are generated outside the cell and are transmitted through a vacuum-boundary wall. In one example, one vacuum-boundary wall is first contact bonded to other ...
