I have about a dozen of SP optics from argon and mixed gas lasers that
require identification and I was wondering if anyone ever had a list
of Spectra-Physics optic identifiers that would cover argon and
related laser optics. It would be excellent to learn optic curvature,

I noticed in a recent post that you work at Sandia Labs. When I was in
high school, back in the mid-80s, I went to school with a kid whose Dad
was a researcher there. Do you recognize the name, Grotbeck? I'm not
certain of the spelling.

I was recently taking photos of my home built Nitrogen Laser pumped dye
laser. The dye laser itself is incomplete as it does not yet have a
diffraction grating installed. And has instead a first surface mirror
placed directly on one the side of the cuvette This was because of the

I am looking for "medium" grade polarizers, say between Polaroid sheets
and nice calcite Glan Thompson prisms and I won't be using high power
lasers.  Anything say around $100?  For the money one spends on a
Newport Polarcar or a polarizing beam splitter, one may as well buy a

Besides my on-line version of my article on the Human Cytome Project and
the application of cytomics in medicine and drug discovery I now start an
article on a concept for large scale cytome exploration. It is at this
moment just the beginning

I have a few of these Terabeam communication transceiver systems, Model
6210, that I need to get up and running.  It has all the bells and
whistles, ie. tip/tilt mirror, quad cell detector, IR detector, beam
expander, etc.  Looks like a big fan when put all together.  Can anyone

Would anyone tell me the working principle of PZT, is it feasible to
use it to control birefringence of PM fiber?
thanks thanks

Is EOM work inside sagnac loop?
Seem it is not work and i would like to know the principle.
Could anyone kindly show me?
thanks,

My understanding is the a peltier element has a hot side and a cold side as
current is run through it.  If the polarity of the applied source is
reversed do the hot and cold sides flip?
Can one Peltier element be used for heating AND cooling of a device?

Is there any software which can simulate some optical components?
such as the output signal of a edfa ring laser and etc
thanks

is there a website or other online document with extensive information

I need a neutral density filter for 1064 nm that transmits 1.5% and is 25mm
in diameter.  Any idea where I should look for one of these?  Most seem to
be designed for 400-700 nm and become somewhat non-linear beyond that.
Thanks,

I have a question that I wonder if anyone can point me to
documentation (or another mailing list or newsgroup) to clarify,
that covers UK fibre installations good practise or regulations.
We have installed composite fibre (multi-mode and single-mode) on

Greets to All,
I'm trying to find out if it's possible to mix or get water to turn in a spiral using light/laser?
