Provided is a cell for optically-pumped atomic magnetic gradiometry that includes a first confining chamber containing alkali atoms and configured to receive a co-propagating pump and probe light beam, including pump light polarized to spin polarize the alkali atoms, and at least a second confining chamber containing alkali atoms, distanced from the first confining chamber, and which is also configured to receive a co-propagating pump and probe light beam. Also provided are an optically-pumped atomic magnetic gradiometer including the presently disclosed and a system that includes the presently disclosed gradiometer and a microscopy system.

Provided is an atomic vapor cell, for atomic or molecular spectroscopy, optical pumping, and/or spin-based atomic sensing, that includes a host substrate and defined there within a buried or non-buried chamber laser written in the host substrate without the need of a mask or photoresist, with either planar or three-dimensional geometry, and intended to contain an atomic vapor. Also provided are an integrated atomic/photonic device and an apparatus, in both cases including the presently disclosed atomic vapor cell, and a method for fabricating the presently disclosed atomic vapor cell.

A method for physical random number generation includes the steps of: modulating the gain of a vertical-cavity surface-emitting laser periodically from the lower threshold to the upper threshold and back; maintaining the gain per round trip positive for a longer period than the round trip time of the cavity; maintaining the net gain per round trip negative for a longer period than the round trip time of the cavity, in order to create optical pulses of random amplitude; detecting the optical pulses; converting the optical pulses into electrical analog pulses; and digitising the electrical analog pulses into random numbers.
