Homemade TEA Air Laser

[toadsEATbugs]

@duckythescientist This might sound stupid, but is it possible to light a match with this?

[duckythescientist]

@toadsEATbugs Unfortunately no. The momentary power is extremely high, but the overall energy is too low to do much.

[toadsEATbugs]

@duckythescientist How did you wire the voltage multiplier, and with what kind of caps?

[Demonchld666]

Driver boards from a scanner and a flash unit from a disposable camera? what are you using for the tube?

[duckythescientist]

@Demonchld666 No boards from a scanner. I used a flash unit with a Cockcroft-Walton multiplier.

post maith! Is iontach go hiomlán! mhaith liom ag trácht i dteangacha iasachta! I Wonder más rud é go mbeidh tú a thuiscint hahahahaha seo!

Hi there, mind telling me how did you make it? And any theoretical explanation for this device?

[FesixGermany]

Good work!!!

Well, as always, Sean, you amaze me! I still don't understand how you did that (just like all of the other stuff you and I made when we were younger) But anyway, that was awesome!! :D

well done with very basic components :)

Try a mirror at the rear end, it eill highly improve the power output.

Also try a more powerfull power supply and increase the repetition rate to about 50Hz and pump a dye laser with it. At that repetition rate it will look almost like a CW laser

[hboy007]

nah, I suppose the rear mirror will not drastically improve output since TEA nitrogen lasers are superradiant and the gas is already depopulated when the reflected beam returns. So I'm planning to build a low pressure longitudinally excited nitrogen laser. I can't really remember but the pulse duration is something like t_max = 36 / (1 + 12.8*p) ns with p in bar.

For air pressure 2ns cause a coherence length of less than 0.6m - not the best preconditions for an optical resonator. But with a properly aligned mirror, 80% power could be gained

it did improve mine :)

now i'm working on a CO2 laser from wich i hope to get at least 10W CW and hope to get a cammera working to post the results

Good luck with your low presure ... i reccomend pure N2

[TzerMaan]

If you have done it, please do show it to me , I would like to see it.

[hboy007]

my low pressure N2 laser works, check out my videos on the subject LE N2 laser.

Great homemade laser!

good job
