Homemade TEA Laser Running At 120 Hz.

[GearzVoNKod3]

I'm curious about how these lasers work in high pressure or near-vaccuum pressures. Any information?

[BankaiIchigo12345]

0:05 it isn't JUST an NST. It's an NST and a Capacitor. Forgot that on your equipment list. This type of laser must use a capacitor.

[prototype9000]

does all that have to be sitting exactly on the top of the capacitor cant you just put the capacitor somewhere else

[MadHatterTruth]

that looked cool

[SpecklePattern]

Its tea time already? :)

[TiagoTiagoT]

what frequencies and with what intensities does the body without covers emit? (by the look of the artifacts i would guess it's at least pulsing infrared, though it could just simply be too bright visible light)

Interesting! I have a neon sign transformer and a whole bunch of angle aluminum, I'll have to give this a try someday. I never would've thought that plain air at atmospheric pressure is such a good lasing medium.

[AnselmoFanZero]

Not that easy dude...guess you have found out already all alone.

I have tried to duplicate this setup unsuccessfully with 10,000V supply and a thin glass plate as the dielectric (Scanner platen DK~7.6 about 2.89 mm thick). Inductor is a 26 turn piece of 12 Ga wire. those are the only notable differences however still no joy. Presumably my setup should run at 120Hz un-rectified. Any ideas?

[nylesteiner]

I would say from reading The Professor's website, that your glass dielectric is way too thick. The dielectric should be only a few mils (thousandths of an inch) thick. Thicker dielectrics create too much inductance in the capacitors for the TEA laser to operate.

Thanks for the reply, I had my suspicions about the glass myself. However I am having difficulty obtaining inexpensive (free) PET or other material for the dielectric suitable for the 10KV. I have burned through many materials of varying thicknesses so far. This is why I resorted to the glass. I wonder about using 2 liter bottles cut and laid flat. or would this be too thick as well? Are there any other issues I should keep in mind when looking for materials? Thanks again for your guidance

[nylesteiner]

Go to a copy store and get the clear stuff used to make transparencies for overhead projectors. That is what I have been using. So far it has worked very well.

I would be interested to hear how the 2 liter bottle stuff works. I may try that myself.

Also,  using a lower voltage, in the 4 to 5 kv range, and running at a low rep rate will make things a lot easier on the dielectric. Running 120 hz is tough on dielectrics.

Use a dc hv supply through a 1 meg resistor to get the lower rep rate.

@nylesteiner i made a setup too :( but no resaults... just alot of sparks between the paralel electrodes and a headake from the horible noise. even when i put a glass over the spark gap still sounds loud as hell. i used a transparent protective sheet i have from when i bought my lcd monitor. it is thiner then transparent projector film, but it's like imposible to make it fail. my spark gap can be as big as 1 cm, but just noice, no laser :( tested like 100 diferent gaps, still nothing.

[gadz1000]

what the shit?

[duckythescientist]

Beautiful, mine only runs at about 0.5Hz

[magx1]

What is the rated voltage output for your NST? How wide is your spark gap?

[clerlic]

Does it have UV? Will it give cancer?

[AnselmoFanZero]

Guess most of it is UV-A. No cancer from this kind of radiation. But dangerous for your eyes...

[ThomasCoding]

Dear nylesteiner, I wrote you a private message about some details of this laser, please can you give an answer ?

[BadAndUgly]

I visited his homepage linked in the description here and found building instructions and other info on the laser, check it out!

[ThomasCoding]

I has successfully assembled a laser few month ago. A have some video of laser on my YouTube page. Thanks for the reply.
