Dana, The glow is a side-effect of the plasma. The primary use in H-maser is to split H2 gad into separate H atoms before sent through a state-separating hexapole magnet, known as A-field magnet.
In Rubidium oscillators, you achieve the same plasma glow, but then it is the D-line emission which is the primary goal, where the D1 and D2 lines is dominant and one of them is filtered. For hydrogen, the D-line is way up in 121,6 nm rather than 794 nm and 780 nm of rubidium, so it's not the D-line glow we see from the hydrogen atom. So, the same glow have separate uses and mechanisms.
