TEA Laser Only Three Inches Long

You have to have University or R&D lab type equipment to make these adjustments. This is NOT a home project. At first it sounds simple, but then I relized the facts stated below, and I knew I'd have to have access to such specialized calibration equipment that the monetary cost would be unbarable. So I quit the idea before even buying my first wire or metal rail. Thank goodness I didn't waste any money on something like this. It requires a skilled engineer to even build it!

[BankaiIchigo12345]

Trick is to make the cap discharge not at one spot but along the ENTIRE length of the gap simultaneously for each pulse, for every pulse, for the whole life time of the laser.

Even trickier is to make this laser channel be at an EXACT multiple of the wavelength, with nanometer precision!

And lastly alligning the mirror's angle to within 1 milliradian or better (a few micro radians would be good).

If these conditions are not ALL met, then the laser cavity simply won't lase.

I have to say I think you;re very foolish to HOLD it!

[ConnorY71]

can you put electricity through it?

[TheNuclearWatermelon]

what's the mW of this

[EatMahSkittles]

@TheNuclearWatermelon i think its the COD MW2 i might be wrong though

[onthecuttingedge2005]

I think redesigning it could increase the efficiency a bit.

[tommybshr]

i dare you to stick your tongue in there

[Mato0092]

a finger would be enough X(

[silverska8er]

not to offend anyone but what is the purpose of this type of laser? hat are they used for?

i think its cool and i want to make one but i want to know if it can be applied in any useful manner

[CaptainNorris]

Its normaly used for experiments with UV-Light, because its emitting monochromatic 337,1 nm Light, that is invisble for human beeings.

Long time such lasers were the only source of ultraviolett laser-light.

Sadly I know no practical uses of these Lasers, they are normaly not used in industry and household.

You could use it as a "blacklight"-source, but thats not very comfortable...

[firedude201234]

i believe its mainly just a concept and second theres a lot of satisfaction having built something like this

[2jpu524]

Because this laser produces high intensity pulses of UV light (up to about a megawatt, 500ps to 10ns depending on nitrogen pressure), these types of lasers are used to pump dye lasers, and for florescence lifetime experiments . You can get any color of the rainbow out of a dye laser. I saw many of these in the spectroscopy labs in my university. I even wrote papers, and maintained one myself..

What is the efficiency and maximum input power for these lasers?

[CaptainNorris]

Efficiency is quite low. I think its hard, to make one, which is stronger than miliwatts.

Normally, they have only ~0,1% efficiency, but the highest efficiency reported was over 3%.

This one seems to work rather good. Nice machine.

[supressor2]

u need only a small hv - surge and you have first portable tea xD realy nice

how mutch V u used ?

[Chamtechie]

CUTE! :D

what did you use as a capacitor dielectric?

[duckythescientist]

good job, I've made one too but it's not portable and my rep rate is only once every 3 or so seconds

[EnkiduAk]

I was wondering what you were using as a dielectric? It seems to be more resilient than your standard vapor seal.

[duckythescientist]

I used acetate projector sheet for mine (not this video).

[magx1]

That's really impressive. I like your work.
