N2 TEA laser (very clean set-up ;-)

[AnselmoFanZero]

Hey
As the title says: A simple ZVS driven TEA nitrogen laser...
The laser-plasma is free of arcs and almost perfect. The electrodes can be aligned...2 screws and a spring between the electrodes do the trick.
Measurements and other details in the description of the video:

Nitrogen laser are cool but very dangerous... you must be careful to protect not only the eyes, but also the skin! A technician in my lab had problems only with a simple UV bulb...

BTW a very nice job as always

Hey
I got goggles....don't worry. And why the hell should I lase my skin? ;-)
Even though its more a flashlight, than a laser, as every typical
TEA N2 laser...

And why the hell should I lase my skin?

Accidents can also happen to experienced people and UV radiations are very harmfull for the skin's cells

By the way I had never seen a laser of this kind it is very unusual

 

[AnselmoFanZero]

Right. But I las at paper-targets only. Divergence is so crappy....makes no sense to lase into a room with fog or something like that.

What do you mean? Never saw a TEA-laser before? ;-) utube is full with those...the set-up is crappy most times...but I wanted a nice and clean set-up you know. And plexi aint that expensive!

 

[Arayan]

I've never seen it with my own eyes :angel: ... and even on the web

 

[AnselmoFanZero]

Means you dont have a homemade N2 laser? Thats a must for the DIY-laser-enthusiast man!!!! A must!!!

What is the input voltage/current?
Have you measured your HV side capacitance? (are you using manufactured caps or alu foil separated by a dielectric)?
Electrode length?

I have been thinking of making a ZVS TEA for a while now as well, but other projects (higher voltages ) have come in the way.

A very nice and clean build! Congrats. :beer:

Must be around 10kV...input is 6-10W...cant measure it you know. But what the hell...it runs well. Strong enough to make a dye lase.
The alu-sheets I used toe the 2 caps are 150mm x 75mm 1mm thick...I made the laser, you do the math ;-) actually I dont even wanna know all the exact data...its a 100% DIY laser...fabricatin it is most of the fun. Like LEGO you know!

 

[Gryphon]

Thats really cool, i love the fact you can see right through it

 

[AnselmoFanZero]

Thanks
I just love plexi...if it looks good, no need for a paint-job. If you want it with colors and what not, just paint it. I work in a lab for paints and plastics you know. So its kinda easy for me...as seen on the laser-gun ;-)

I gotta REAL big TE-laser on my second workbench. 1.5m long (4.5feet) 58 doorknob-caps...will take some time til its done, but it will be huge ^^

Hey,

Yeah building is always the fun part.

I should have been more specific with the power input. I meant power input into the ZVS driver. (Volts and amps going from the transformer or power supply).


Best Regards,

[AnselmoFanZero]

Of course...its 12V in @ .5A maybe .65A max
Its a small laser...so the input does not have to be like 200W or so you know. Just wanted a small reliable laser...and good looking of course.

Very good job. Nice laser!

 

[AnselmoFanZero]

Thanks Jarrod.
You have mail by the way ;-)

Nice set up!

337nm is not too bad for the skin. Usually people get freaked out when you get into FHG YAG or Eximer systems at <300nm.
