Title: Atomic magnetometer with multiple spatial channels

An atomic magnetometer includes an atomic vapor cell, an optical system conformed to transmit pump radiation and probe radiation through the vapor cell, and an optical detection system arranged to receive and detect probe radiation after it exits the vapor cell. Improvements in the separation of spatial channels are achieved by using a a diffractive optical element arranged to divide at least the pump radiation into a plurality of separate diffracted beams that traverse the vapor cell.
