    archeometry's IR to Vis Converter

    I got the info couple years back from Kigre Laser in N.C., Los Alamos developed the LIBS unit for the rover mission on Mars...during a test, some visiting scientists were viewing this pulsed Nd-Yag Libs unit, not everyone in this room had safety glasses. The guy from Kigre said the pulse...

    archeometry's IR to Vis Converter

    Here is the prototype ceramic material, should go to 1600-2000 deg F and would be mounted on a refractory spatula of alumina or equivalent material.

    archeometry's IR to Vis Converter

    From the photo based on intensity of the dots 10-20% reflection...take piece of sandpaper and sand off the plastic coating...and see what happens..

    archeometry's IR to Vis Converter

    The device was designed for 785nm for high power density 5Kw/cm2 or better and Raman laser systems. Also there is a plastic coating over the matrix that can be removed and because you see reflection at 473nm doesn't mean reflection in the IR. Hence mirrors made out of polished silicon for IR and...

    IR-Visible Laser converter

    I made the device for 785nm and found that it goes to 980 and possibly to 1064nm. The Raman laser i made this for has a head with a virtual focus point 7mm in front and pinches the beam to 100micron dia. This at 300mw output 100 micron beam will burn wood...and doesn't burn the anti-stokes...

    IR-Visible Laser converter

    Those wimpy laser converter cards are cheapo and low temperature narrowband and not designed for POWER DENSITY. This gizmo uses another class of material and will withstand W/cm2 and has wide broadband range..I use a dangerous level IR Raman system that will burn carbon material, etc.and your...

    New Antistokes Material IR-Visible Converter

    laserbee, do you wear safety glasses at rated blocking laser frequency and see results with radio shack device, or are you bare eyed?..answer this, because you know IR does retinal damage...post some pics of the Radio Shack card viewed through IR blocking goggles from your CCD camera...ok...

    New Antistokes Material IR-Visible Converter

    Also the Radio Shack stuff is phosphors used in color TV's..Zinc Sulfide, etc. And that material used in detector assemblies in Nuclear, etc for alpha, beta scintillation , Spinthariscopes....lo mismo....basically old tech...archeometry

    New Antistokes Material IR-Visible Converter

    This is how state of art it is, trying to find a CZ reactor to grow crystals of this material.similar compounds are superconductors at LN2 temperatures. Nobody has any crystals grown of this material...real time right now, i'm trying to find a shop who does CZ growth on small scale to try to...

    IR-Visible Laser converter

    what range of frequency in IR and do you wear safety glasses while viewing beam? this converter gives a good response while wearing glasses...send the pics, response profile, etc...is the device safe or are you bare eyed while viewing?..archeometry...live in Mississippi and have a high tech lab...

    New Antistokes Material IR-Visible Converter

    I have been working with an IR Raman 785nm system for about 2 1/2 years now. It was always frustrating not being able to see the beam except with a CCD camera. A few months back i started looking into this behavior and found a new material that up-converts the IR energy into visible range...

    IR-Visible Laser converter

    yeah, i have pics and yes you could write review, i have nothing to hide and i'll send you free sample to test for yourself..how about that?...DW...i'll put another pic or two up..they rejected my first pics from size so i have to re-duplicate experiment at lower pic quality...gimme 15 minutes...

    IR-Visible Laser converter

    yeah, no problem, i'll send a good unit for free, but i can't keep on sending free units, these cost me a few grand in bucks and my R&D time i have to suck up which is more than a few thousand...send your address to my email and i'll send the device, you'll be intrigued, but you would be very...

    IR-Visible Laser converter

    I make these devices by hand and are optimized with a two stage reaction which enhances the glow. Detection mw level is extremely low into the 1mw or less range. Germany and Japan sell these devices only rated at 980-1064nm range for 350-450$ each. The interesting part is when wearing the safety...

    IR-Visible Laser converter

    Hi, I have a small Hi-Tek lab using Raman IR system @ 785nm. I was always wondering how the beam profile was, since there is a virtual focus point and beam divergence. The result is a device you can see the beam. See attached photos. Wearing the safety glasses the beam scatter is in Blue...
