Home Made Baking Soda Laser With Improved Performance

I made some adjustments to the cavity mirrors, and I was really surprised to see a big difference in performance. It will burn glass now!

Modulating the current through the gas(1khz +) will result in more quantum collapses, thus more net power out . ..just a a little tip from 'ol Truckin'Mike.

I dabbled with CO2 lasers back in the days before internet. Review Stefan–Boltzmann law. And Planks constant

@TruckinMike1965

I'd like to build a RF driven laser, but I'm not sure how to approach it. I'm not sure what is different with these devices. Perhaps cooling is not an issue to the extent that it is when direct electrical discharge is involved. Anyway - interesting prospect I've thought about.

How manny wats do you use and how many volts. The resistance in the gass must be huge or is it somthing with the mix of the gass that make it more conductiv? If you tried with pure CO2 would it be more or less resistance? And do you use pessure less than Atmosferic pressure/1 bar?

@nanus102000

15kV@60mA

CO2 is only a percentage. Nitrogen (air) is also present. The addition of helium makes the entire laser work better. It also makes the gas more conductive. Pure CO2 will not work.

@magx1 thanks for reply, it helps to make me understand it.

Have a powersuply on 29kv and 0.005172 A.

How would mix the gasses to get a infrared lasser?

Yaeh I'm stupid and can't find it out myself.......

[magx1]

@nanus102000 Not sure. It would depend upon other variables. My power supply is only 15kV, but it's rated at 60mA! The power supply is deadly.

Google "Sam's Laser Faq" and go to the "Comprehensive Table of Contents". Scroll around and find the section on "Home-built Carbon Dioxide (CO2) Laser". This will probably be your easiest place to start. Keep in mind that these devices are dangerous, and the power supplies are instantly lethal.

you sound like george bush

@ENDORPHMAN

Thanks!

Isnt there a burn mark or a scorched hole in the wall on the other side of the room? haha

Snazzy laser

4:05 you sound like your trying to do a russian accient! :p

[mikeccuk2006]

Nitrogen- get liquid nitrogen

CO2 - Fire extinguisher

Helium - balloon tanks

Everyone can make lasers, here comes WW3

[NOTy0urPUPPET]

I hope your weartng laser safety goggles.

bong?

[UtahBraten]

so this is what bush did all the time

[brodie1709]

must be an intresting conversation piece.
