some weird things I picked up today?
the batt. is for size
is it a glass fiber?
perhaps a CO2 or really high power laser fiber coupler?
is there any optics in the heatsing assembly?
175 watt or 300 watt high pressure cermax lamp assembly WITH fiber
CAUTION< FILLED WITH XENON AT VERY HIGH PRESSURE< WEAR FACE PLATE/GLOVES WHEN HANDLING/USING.
DO NOT OPERATE WITHOUT COOLING. YES I AM SHOUTING. I USED TO USE THOSE IN THE LAB, 6 of THEM.
PRODUCES EXTEREMLY BRIGHT UV AND IR IF NOT FILTERED>
NOT A TOY! CAN BLIND YOU IF YOU GET THE THING CLOSE TO YOUR FACE
48 psi internal pressure cold, God and ILC Div PE only knows how high when running. NOT A TOY!
While much safer then quartz lamps, if not filtered can fry tissue.
Arguably one of the highest irradiance light sources on the planet.
That size is a .65 mm arc gap with built in precision ellipsoid or parabolic reflector for focusing into the fiber. Some have a blue dental curing filter built in, others are for in body illumination when they have that fiber assembly bolted to them.
Steve
Thank you Steve!
I am wrapping it up and putting it away,,
Again thank you Steve!
wow frightening suntan-tatoo jackhammer here!
why is not Belgium a place where you can find unique items too? I wish I lived in california or any other technological place in US
Thank the gods that you do not have to deal with the FDA.Quote:

Lets put it this way, if we did not have lasers we'd all want cermax lamps, closest thing to a incoherent laser, and plenty of visible light as well.
Yes, you can burn stuff with them, and they are fairly common, used for things like movie projectors,studio photography, DMD stuff, tank headlights, instruments, mega strobes, special effects, plant growth etc. They come in sizes to 4,000 watts. If you've seen a picture taken inside the human body, odds are the source was a cermax with that big fiber, BTW the fiber is a add on, not part of the lamp. 6200 K color temperature.
One of my former students had the misconception that laser safey goggles would stand up to a filtered cermax, they did, for a few minutes, then he melted a hole in a 400$ pair of goggles.
Beg to me, and I mean really Beg and Grovel,, and I might bring one to Selem.... One 300 watt cermax WILL light up that auditorium.
My bet is there is used technology in Belge.... You just don't know where to look, yet.....
Find some ham radio operators, they will know where to look.....

It costs gas money to haul all that gear to SELEM, I need to pick and choose what I drag out there. I'm already looking at hauling the trailer up and down the mountain. And down with a trailer with no trailer brakes is starting to scare me.
Y'all SELEM locals, Is there a way to avoid the 5 mile hill (don't know what u call it) without driving 200 more miles?

Judging by the connector, I would say it is some kind of telecom laser.
Ahh,okQuote:

In the winter they have wrecks along that stretch all the time - many of which are bad enough that they have to close the Interstate.
And no, there's no easy way around it. (Unless you fly.)

Oh, so THAT is what you "flatlanders" call that stretch of road!! :p
One good thing about traveling it in August -
If it rains, that stretch sucks; but if it snows, it REALLY sucks!! :eek:
Which SHOULDN'T be a problem in August.... :D
I always thought that was just a normal road.
I guess born and raised here, nothing to compare it to.
A flat straight road for miles on end......how boring.
How many volts/amps does a lamp like that require?
I'll take a guess at 30V 10A. I think a starting pulse is also required.

Also cloned recently , after patent(s) timed out, by hammatsu and GE.
Steve
wow thats pretty low... I was thinking like arc lamp current/voltage levels.
Could one of these be used to pump a YAG or similar rod? Seems a bit more efficient than an arc lamp... but then again it could be a lot weaker. I'm not really sure of the wattage rating of arc lamps. To be honest, I really dont know a whole lot about lamp pumping in general.... *warn*warn:D *retardo
the schematic given in this document is quite interesting
thanks for these informations :)

yags are usually pumped with a krypton CW arc, which puts out huge amounts of IR at the right wavelengths, and very little visible light,
would need to be filled with krypton, to get the 810 nm band , to really pump yag well. I'm sure it could be done, with a yag slab, but never seen it done.
Steve
Weeell.... it *is* an arc lamp, just a really really short arc lamp made out of some kind of ceramic unobtainium.Quote:

And he is not even professional!Quote:

I still wish there were some nice surplus places in our little country
I found some very nice chocolates last time I was in Belgium.:D
not to mention beer... *retardo
Well, I'm belgian and I found just this year 1 green dpss, 1 blue dpss, 2 aom, 4 50/50 beam splitters, multiple optics, dichroics, gold and silver plated hexagonal mirrrors and 10ths of first surface mirrors, waveplates, polarizers, ....
You just have to know where to look. (I just looked in the scrapheap at work :) )
Where do you work?Quote:

a photofinishing company in east-flanders.Quote:

Hmz, If you have anything for sale just let me know :)Quote:

belem is in the planning for sure ;)
yeah that could be done :) I was planning to organize a meeting with laserfreak members this summer if I have my house (big affair, chances are leaving one by one for me to get this house, this is the quest of the graal...)
I'd have combined laserfreak and photonlexicon to achieve higher power :D
