 note = {We developed a subtraction circuit to measure the saturation spectra of rubidium atoms without using a lock-in amplifier. An instrumentation amplifier (IA), which is a type of differential amplifier, was used. We designed our IA to have an adjustable gain of 4.3 - 21 to obtain saturation spectra with a good signal-to-noise ratio. With our IA, we tried to deduce the saturation spectrum by subtracting the Doppler signal from the transmission spectrum of rubidium atoms enclosed in a glass cell. As a result, the obtained saturation spectra have six peaks originating from the atomic and cross-over resonances, and their line widths are 11.2 MHz. This number of peaks is the same as that detected with a lock-in amplifier, and the line width is smaller than that detected with a lock-in amplifier. Therefore, we confirmed that our IA has equivalent performance to a lock-in amplifier for measuring the saturation spectrum of atoms., text, application/pdf},
