| Abstract | The design of single chip current source based on a common power operational amplifier is presented and demonstrated for the purpose of controlling applied magnetic fields using bias/shim electromagnets in cold atom experiments. The efficacy of the design is realized via application to red-detuned polarization-gradient cooling of \(^{87}\)Rb down to 3 \(\mu\)K. Further, we demonstrate Raman spectroscopy using these devices to apply current and so generate a precise, accurate, and reproducible magnetic field. This work is intended as a short tutorial for new graduate students and postdocs of laser cooling and trapping. |

amplifier is presented and demonstrated for the purpose of controlling applied
magnetic fields using bias/shim electromagnets in cold atom experiments. The
efficacy of the design is realized via application to red-detuned
polarization-gradient cooling of $^{87}$Rb down to 3 $\mu$K. Further, we
demonstrate Raman spectroscopy using these devices to apply current and so
generate a precise, accurate, and reproducible magnetic field. This work is
intended as a short tutorial for new graduate students and postdocs of laser
