That's called coherent population trapping and is used by the
chip scale atomic clock (CSAC) from symetricon (although they use
it with caesium instead of rubidium).
You can find in [1] a quite good and easy to understand explanation of
the physics of an Rb based clock. It also contains an overview of what
is currently known to be possible and where some of the problems are
