Hi all,
Can anyone tell me the difference (if any) between a pockels cell and a photoelestic modulator? Thanks.

Do you also have a Pockels cell and a photoelastic modulator?
Cheers

I'm relieved to hear that you aren't living a double life. ;)
PEMs are sort of the low-frequency limit of an AO cell. They're excited
at their lowest longitudinal resonance (like an organ pipe), and the resulting stress birefringence makes it into a wave plate, like a
Pockels cell only much much slower. The good news is that the
birefringence is much more uniform over their apertures--Pockels cells
are the pits that way.
PEMs are a good match for lock-in amplifiers in student labs--I'm mildly surprised that you folks don't sell them.
It's irrational week--we had Pi Day, the Ides of March, and are now
passing sqrt(10) on the way to St Patty's tomorrow. ;)

So the birefringence is modulated at the drive frequency?
I think I've seen these at trade shows.

Grin. After 70's F in LA, I'm back to drifts of snow at the bottom of
my drive way. I am so ready for this winter to be over... though
I did drag 'the boy' out back for some sledding. With 2' of snow still
on the ground I figured we might as well use it for something.
