Latest Patents

Fancher holds a patent for a "Continuous, velocity-controlled three-dimensionally laser-cooled atom beam source with low fluorescence." This innovative method and apparatus are designed for producing a cooled atom beam suitable for applications requiring cold atoms. The invention employs a two-stage cooling process, where atoms in the beam are cooled in two spatially separated regions of a cooling apparatus. Initially, the atoms are cooled in two dimensions by two counterpropagating laser beams under a magnetic field. Subsequently, they are cooled in three dimensions using optical molasses. The power, frequency, and magnetic fields are finely tuned to achieve a continuous beam of three-dimensionally cooled atoms with a controllable velocity distribution, very low decoherence, and minimal background atomic gas loss.
