A fully stabilized Brillouin spectrometer with high contrast and high resolution.
Using a triple-pass plane and a confocal Fabry-Pérot interferometers in tandem, we have constructed a Brillouin spectrometer with a frequency resolution of 10(8) and a contrast of more than 10(10). Our system is controlled and fully stabilized by a desktop calculator, allowing efficient data collection for very long integration times.
