Abstract
A method and system that includes injecting light into a vapor cell; detecting an output of the light from the vapor cell; modulating the light injected into the vapor cell in dependence on the detected output to achieve an oscillating signal; applying an energy pulse to the vapor cell prior to achieving the oscillating signal to decrease a time required to achieve the oscillating signal; and determining a magnetic field measurement in dependence on a frequency of the oscillating signal.
