gas laser in the 1960s in technology that later revolutionized surgery
and made possible compact-disc players and grocery-store scanners,

I have a question and I thought someone in this group might have some
experience with this.
I am trying to setup a confocal  fluorescence microscope and would
like to use a dichroic mirror to separate the collected fluorescent

I've got a couple of projects going here with XY tables and lasers.  One
is an old HP XY plotter that I've gutted and retrofitted with a simple
step/direction stepper motor driver and a 4W 980nm fiber coupled laser
diode.  The other is an hacked Fuji gel plate imager that I'll be ...

I'm studying strain effects on semiconductor materials and i've found
that strain remove degeneracy in valence band:  tensile with lh upper
to hh,  compressive with heavy-holes upper to light-holes. I don't
understand the effects on bandgap: for example tensile compression

I need to find a device that help me to analyze light intensity
distribution that comes out from very thin waveguide (approximately 1
micrometer). Additionaly such a device should works in NIR spectral
range (from 1000nm to 1600nm).

Sorry it's been a long time since I've been on this group, and I
apologize for the sudden appearance. I swear I'm not like that one
particular family member that only calls when they need something....

I have been a member in good standing with eBay since 1999.  As readers
of Sam's Laser FAQ are probably aware, I have acquired a large number of
lasers and related items on eBay, most at bargain basement prices.  All in
all I have been very satisfied with the eBay experience.  Until ...

I read in a book concerning the famous (to some)
17th Jesuit scholar Athanasius Kircher

that the science of optics used to be symbolized by

we have a 1990's Cynosure customized model LFDL-3 dual head, flashlamp
pumped dye laser, which uses L-6341 flashlamp (990-6000-605 Cynosure
part#). we are in desperate need for at least two new (or used)
flashlamps for this laser. does anyone know where we can buy these

Finally, after a few months looking for spare parts my leitz sm-lux is like
new (well... let's say, almost like new...)
I had to have a custom gears manufacturer to make a new focus gear (spare
part impossible to find, cost: 120 euro), to find a new holder (on ebay...

We are renovating a just-bought (old) house, and I'd like to run as many
wires through the walls now as I can, so as to not have ugly "rat-nests"
later...
The basement is likely to house the "heavy" computer equipment (like
