An optically pumped magnetometer is a highly sensitive device that measures magnetic fields using the principles of optical pumping and atomic spin resonance. It is widely used in applications such as geophysical surveys, medical imaging, and fundamental physics research due to its ability to detect extremely weak magnetic fields without requiring cryogenic cooling.

Optical pumping is a process used to transfer energy from light to atoms or molecules, aligning their spins to create a non-equilibrium distribution of atomic populations. This technique is fundamental in applications like laser technology, atomic clocks, and quantum computing, where precise control of atomic states is crucial.

Cryogenic cooling involves the use of extremely low temperatures to preserve, stabilize, or enhance the performance of materials and systems, often employing liquid gases like helium or nitrogen. This technology is crucial in fields such as superconductivity, space exploration, and medical preservation, where conventional cooling methods are insufficient.
