Investigation of microwave transitions and nonlinear magneto-optical rotation in anti-relaxation-coated cells [PDF]
, 2004 Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of $^{85}$Rb and $^{87}$Rb atoms contained in vapor cells with alkane anti-relaxation coatings.

Compact and frequency stabilized laser heads for Rubidium atomic clocks [PDF]
International Conference on Space Optics — ICSO 2012, 2017 We present the development and complete spectral characterization of our compact and frequency-stabilized laser heads, to be used for rubidium atomic clocks and basic spectroscopy. The light source is a Distributed Feed-Back (DFB) laser diode emitting at 780 nm or 795 nm.

The 87Rubidium Atomic Clock Maser in Giant Stars [PDF]
Research Notes of the AAS, 2018 We conducted a Green Bank Telescope search for the ground state 6.8 GHz hyperfine transition of rubidium ($^{87}$Rb) toward giant stars detected in Rb I optical resonance lines. The spin-flip transition of $^{87}$Rb is one of the principal transitions used in atomic clocks, in addition to the hydrogen 21 cm maser and the $^{133}$Cs hyperfine transition
