Abstract
A light pulse interferometer includes a first atom source and a first laser. The first atom source is configured to direct a first group of atoms in a first direction. The first laser is configured to generate one or more interferometer laser beam pairs. The one or more interferometer laser beam pairs interact with the first group of atoms in an interferometer sequence of three or more pulses to produce atom interference. A first laser beam pair of the one or more interferometer laser beam pairs is disposed to interact with the first group of atoms to perform 1D-cooling and velocity control of the first group of atoms prior to the interferometer sequence.
Claims22
A light pulse interferometer, comprising:
- a first atom source configured to:
- direct a first group of atoms in a first direction to pass through the light pulse interferometer;
- and
- a first laser configured to:
- generate one or more interferometer laser beam pairs, wherein the one or more interferometer laser beam pairs interact with the first group of atoms in an interferometer sequence of three or more pulses to produce atom interference within the light pulse interferometer, and wherein a first laser beam pair of the one or more interferometer laser beam pairs is disposed to interact with the first group of atoms to perform 1D-cooling and velocity control of the first group of atoms prior to the interferometer sequence.
A method for a light pulse interferometer, comprising:
- causing directing of a first group of atoms in a first direction from a first atom source to pass through the light pulse interferometer;
- and
- causing generation of one or more interferometer laser beam pairs using a first laser, wherein the one or more interferometer laser beam pairs interact with the first group of atoms in an interferometer sequence of three or more pulses to produce atom interference within the light pulse interferometer, and wherein a first laser beam pair of the one or more interferometer laser beam pairs is disposed to interact with the first group of atoms to perform 1D-cooling and velocity control of the first group of atoms prior to the interferometer sequence.
A computer program product for a light pulse interferometer, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
- causing directing of a first group of atoms in a first direction from a first atom source to pass through the light pulse interferometer;
- and
- causing generation of one or more interferometer laser beam pairs using a first laser, wherein the one or more interferometer laser beam pairs interact with the first group of atoms in an interferometer sequence of three or more pulses to produce atom interference within the light pulse interferometer, and wherein a first laser beam pair of the one or more interferometer laser beam pairs is disposed to interact with the first group of atoms to perform 1D-cooling and velocity control of the first group of atoms prior to the interferometer sequence.
