Abstract
A continuously tunable radio frequency (RF) sensor system is provided. The system includes a pump laser system that includes first and second pump lasers, at least one frequency modulator to modulate frequencies of first and second laser light from the pump lasers to first and second select frequencies, a switch system to selectively pass one of the first and second laser light, an amplifier to amplify the passed laser light, a frequency doubler to double the frequency of the amplified laser light to generate pump light. A laser source lock system is in communication with the pump laser system to ensure a frequency of the pump light is referenced to atoms in a vapor cell and provide a probe light. The pump light and probe light are transmitted through the vapor cell. A detector measures the probe light that passed through the vapor cell.
