  • Method of creating an optical atom trap and atom trap apparatus, employing an incoherent light field
    Patent number: 12131834
    Abstract: A method of creating an optical atom trap comprises the steps of providing an incoherent light field with a light source apparatus, by creating a pulsed laser light beam of laser pulses with a repetition rate equal to or above 100 kHz and a relative spectral width of 10?4 to 10?2, coupling the pulsed laser light beam to an input end of a multimode waveguide device and guiding the pulsed laser light beam by total internal reflection to an output end of the multimode waveguide device, wherein the incoherent light field is provided at the output end, and creating the optical atom trap for trapping atoms in an atom trap chamber device by coupling the incoherent light field to the atom trap chamber device, wherein the optical atom trap has a trap frequency and the atoms have multiple resonance frequencies, and the laser pulses for providing the incoherent light field are created such that the repetition rate is above the trap frequency and the spectral width is below a spectral range between the resonance frequenc
