1. A beam delivery system comprising:
a beam delivery photonic integrated circuit comprising:
one or more optical inputs;
a plurality of waveguide outputs, wherein each of the plurality of waveguide outputs are tapered;
a plurality of beam paths, each beam path connecting one of the plurality of waveguide outputs to at least one of the one or more optical inputs,
wherein at least one of the plurality of waveguide outputs that is connected to a first optical input of the one or more optical inputs is directed to a photodetector configured to measure an intensity of the waveguide output directed to the photodetector,
wherein each of the plurality of beam paths connected to the first optical input comprises a respective optical element configured to provide a respective beam having a respective power that is substantially constant by removing power fluctuations from the respective beam provided via a respective waveguide output of the plurality of waveguide outputs based on the intensity of the waveguide output measured by the photodetector, and
wherein the beam delivery photonic integrated circuit is on a chip;
a telecentric optical relay assembly, the telecentric optical relay assembly configured to receive beams provided by at least two of the plurality of waveguide outputs and focus each received beam on a corresponding one of a plurality of positions of an atomic object confinement apparatus in a telecentric manner.
