"The SA.45s reportedly provides ... short-term stability (Allan
Deviation) of 2E-10 @ 1 sec, long-term aging of 3E-10/month"

Neat, but only really of benefit to *really* space/weight/power critical
devices.

"The cesium atoms are “excited,” or heated to a vapor state by a beam
generated from a vertical-cavity surface emitting laser (VCSEL) that
passes between upper and lower polymide heater/suspension strips. The
VCSEL was designed by Sandia Labs, one of Symmetricom’s partners on the
CSAC team."
