Hi Bob,
Some time ago Hoptroff produced a Cs pocket watch using the Symmetricom
SA45s - now how long for a wrist watch !!

Hi
So the wrist watch sized fountain that was promised 15 years ago isn’t gong to

Hi Rick,
They did not mention the complexity of the laser system they needed, especially
considering that the optical bench of a fountain isn't all that small, and also
because they want to de-tune lasers. While they seems to have an idea, they
didn't touch on that subject.
Nice to see that people think in a different way thought.
Looking forward to see the progress on this one.
Cheers,
Magnus
