Gallium GB

I, long ago made lasers with Selenium and also with Cadmium, these needed to be melted in a "side pipe " of a gas tube of low pressure Helium or other inert gas.  As these were multiple wavelength lasers the best gas envelope was at least 16 inches long, and used two Brewster angle end windows for the beams exits.  They were powered by 12KV to 18 KV from Neon sign transformers.  These were farily easy to make as long as you could lower the internal pressure with a vacuum pump, and seal around the electrical anode and cathode, I used uranium glass which adheres to the tungsten electrodes and to the quartz tubing well, and found the biggest technical problem to be finding proper eye protection from the many different visible and invisible, (IR & UV) wavelengths emitted simultaneously from the two ends at several dozen mW per wl.  So, yeah, can you look into adding in Cadmium?   :-X
 





I am currently looking for several ounces of uranium-235. Cost is no issue.

How much is overnight shipping to kazakhstan?

Yes, I will look into it. I'm not sure about shipping regulations, however, as cadmium is toxic, but I'll find out, and do my best.

HAHAHAHA nice! But, good sir, you have not read the rules... I believe that uranium is radioactive. Check your local hardware store, they may have what you are looking for.

No, that's what the marijuana is for.  Don't think i'm an idiot...   Death to the infadel!
 
Got my Gallium today.  

Surprisingly it made it without having melted in transit.  

Cool stuff.  

Thanks again for handling the buy!
