Higher harmonic detection of rubidium employing wavelength modulation spectroscopy. The peaks correspond to the hyperfine structure of the 780 nm transition in rubidium-85 and rubidium-87 isotopes. (a) Absorption spectrum of rubidium, (b) first harmonic detection, (c) second harmonic detection, (d) third harmonic detection, (e) fourth harmonic detection, and (f) fifth harmonic detection.
