Hi,
I actually use a Renishaw ML10 / EC10 for interferometry at work.

Hmm. I think I have all the parts for this. Except the programmable polarizer.

Hi!
I have collected some hyperfine splittings into a table with references.
I was reminded of this when asked offlist for the Rubidium
Please see the link below - gives quite a good explanation of laser cooling.
There are more detailed texts available at NIST in the US and NPL in the UK.

Hi,
What would be a good method of using my Z3801A 10MHz out put to adjust the
oscillator adjustment dial on my 8130 Spectracom Frequency Standard Oscillator.
When I use the 8160A Spectracom NSB frequency Standard Receiver WWVB it has a
frequency calibration feature which allows a local

Another way is to use an oscilloscope to watch the drift of the Z3801A
versus the Spectracom. You can set the scope up to show a Lissajous
display, or just use one signal to trigger the scope while viewing the
