[time-nuts] What does determine the short term stability of an Rb vapor cell standard?

Moikka moi, In the past, it has been again and again claimed that the HP 5065 has such an outstanding short term stability because of its large vapor cell. But the more I read, the less I believe this. E.g. if you look at the papers by the group around Gaetano Mileti and Christoph Affolderbach

Could it be that with the narrow-band laser emission the dip in light transmission of the Rb cell is significantly improved? I know that diode lasers are generally not paragons of virtue when it comes to intensity noise, so I'm wondering what accounts for the claims of better SNR with laser
