Does Anyone have Gas Formula for A 130 W CO2 Laser He, N2 Co2,.. ?

I believe the gas mixture for a sealed CO2 laser is proprietary consisting of He, CO2, N2, Xe, etc.

You may want to consider converting this tube to a flowing gas laser. The gas is commercially available from welding supply outlets. A flowing gas laser would require a vacuum pump.

Hum, that was my sig, which is the only part of the service at my church in the original Attic Greek. "Come to us Lord God!, Come to us Christ!."

Alright, this is difficult.

For a flowing gas Co2, a starter mix is 9.5% CO2, 13.5% N2, and 77% He by pressure.

However the ratio of Co2 to N2 is critical in determining power. That changes with the tube design,

In a sealed Co2, a trace of hydrogen, say 1-2% is often added by replacing a small part of the Helium. This activates the catalyst that regenerates the gas, if installed. This may be added by either using pure H2, or a trace amount of H2O. Too much H2O is going to readily damage the optics.

Carbon monoxide is often added to the Co2 portion of the mix to stabilize the dissociation of Co2 by the Discharge. CO also lases, so there is not much power lost by this move.

Xenon is added, 1-2%, to regenerate the gas as well. Failure to add a regenerative gas will result in a very short life of the Gas Fill.

So You have Co2,N2,Xe,CO, H2 or H2O, and He going into the tube.

In other words, I don't exactly know what you should ADD fot that tube. . You will have to tweek the Co2-N2 ratio for best power.

Normally a sealed tube will have at least Co2,N2,XE,HE.

Did you try Parallax technologies for the refill?

There is a thread in this forum regarding the topic of converting a sealed tube to flowing gas:

Thank You for any Support, White Light ''

No problem. I just wanted to discover your aims and get them out there because you'd be surprised at some of the uses proposed at times and so sometimes people can be reluctant to help with these items.

Thank You Everyone for the advise, it is much needed ,.. rather than making a flowing gas laser out of these PARAGON 100 - 130 W lasers,.. they only have one bleeding Valve at one End,.. what must i do ,... open the other end to alow the gasses to travel ,.. lock it down and Vacuum ,.. or ,.. is it ok just to fill with new mix and re: Vaccume to + or - 4,6, Torr ,.. what are your thoughts,.. ????

[mixedgas]

Does your tube have a mechanically sealed refill port (called a valve actuator), a sealed off glass fill stem, or a metal pinched fill stem?

That matters in how the tube is reprocessed.

Also how the optics are sealed on matters, ie If you can bake out the tube at vacuum before refilling.

In any case you will have to flush the tube many times while starting/restarting the plasma.

It has a metal pinched fill stem. it is the (( PARAGON )) 100 (( Watch )) the Video i just put on Youtube,.. Paragon 100: http://youtu.be/xb4PoBoGTp0 Also i will be selling One i have two of these Unit's

Thank You

It only has One fill port up front on the lens side ,.. what do i do ,.. slightly open the 8 hex bolts and after it's filled tighten the bolts and vacuum. Paragon 100: http://youtu.be/xb4PoBoGTp0
