amateur visible laser made out of ordinary laundry detergent

I dont understand this can you explain this to me please?

LOL - brilliant!

[kungfumaster12]

where is the liquid detergent at? is it in the clear cylinder diluted in water or something? or is th detergent being vaporized in the air? like a fog machine?

[Morgotheenslaver]

Oh my god, what a cool hobby. Do you have an instructional video of making your basic TEA laser?

[TheNuclearWatermelon]

Is that why white T-shirts glow blue under the Blacklights you see at parties?

[magx1]

@TheNuclearWatermelon

You are absolutely correct! If fact, a white T-shirt makes an excellent target for the invisible UV beam from a nitrogen laser. It is the optical brightener that also makes the T-shirt look more "white" in normal lighting. Without the brightener, the white shirt would not seem as bright in ordinary light, and would actually look more yellow to the eye.

lol...too funny. OMG that was wicked cool. Laser Soap. You said you were powering that with a Neon sign Transformer, but it looks like a Bug Zapper Transformer in the Video. How much juice were you feeding into this thing to get it to work? And thanks for posting this, a great project to try.

I want to make a laser and I have three 56 in. long 1/2in. diameter glass tubes. I only need one, so if somebody else wants one, I'll sell it - contact me.

I have one of those tubes and I have access to liquid nitrogen. What else would I need to make a laser similar to the one you have here?

Things I have -

-A healthy supply of aluminum foil

-A roll of overhead transparency

-A place where I can get some liquid nitrogen (maybe argon)

-The glass tubes

-Easy access to most common chemicals

[ChrisKarr]

Oh, I also have some transformers, as well. I'm a Tesla coil builder, so I've become quite resourceful.

[ChrisKarr]

Wow. You're a slut. Go to hell.

[hboy007]

great video :)

[hboy007]

erh... I forgot to mention: you can get more output using a few turns of copper wire as an inductor instead of the resistor.

Lot of smoke used :P

[DrMario2007baka]

magx1 - I guess you maybe would want to try 211 nanometer or lesser in pumping light wavelength, maybe from Iodine-Xenon laser. Who know... I haven't tried - maybe I will get to it.

(Also, theoretically, the car coolant MIGHT lase, who know? If you want to do it, don't mix it with water, just use rubbing alcohol - Also, grab a radiator if you want 1,000 watts of green laser light from it. O___O )

[magx1]

Pumping with 337 nanometers gives a visible output from the dye. If lasable when pumped with 211, the resulting output might still be in the UV.

For transverse pumping, concentration must be strong enough to absorb all of energy < 1mm from inside surface of cell. Not sure that the dye in antifreeze has a high enough concentration to do this. It's worth a try: anybody willing to try it (or any other common substances), please post results here! Feedback is welcome.

[duckythescientist]

wonderful, I really need to try a higher repition speed for mine and some of that dye.

[magx1]

Do you have a supply of nitrogen?

[duckythescientist]

no, not yet. I'd love one but I'm only a freshman in highschool without a job. If I had a greater disposable income then I would. Maybe later.

[mytubedude532]

Brilliant Good Job!

i have read that plant based dyes work-try boiling down some voilet flowers....or other brightly coloured plant matter...red cabbage maybe?

[magx1]

Thanks. I am told it is possible to lase Chlorophyll. So I tried an experiment: I soaked monkey grass in 91% isopropyl. The result fluoresced cherry red under black light, but I was unable to make it lase. I will keep what you suggested in mind. Where did you read about plant based dyes working in lasers?

[labidus74]

Nice lazer!
